This is a solution - How to install XP on Satellite L40

Question

NOTE: you will need a license for XP Pro SP2(it should work with Sp1 and Home, but runs better on Pro SP2)!
First download and install nLite. http://www.nliteos.com/download.html (Requires .NET Framework 2.0, you can download the .NET Framework from here: http://www.microsoft.com/downloads/details.aspx?FamilyID=0856eacb-4362-4b0d-8edd-aab15c5e04f5&DisplayLang=en
Now download and extract the slipstream drivers http://files.soulpass.com/acer/slipstream_drivers.zip to a folder like C:\Drivers-temp\
Insert your WinXP install disk, cancel out of the autorun if it pops up.
Start up nLite, click next on the splash screen. Tell it where your CD is. It will ask you to tell it where to cache the files at. You can just use a folder like C:\XP-temp\ for that.
On the Presets screen, click Next again. Now click on the Drivers button, as well as the "Bootable ISO" button, then click "Next"
On the Drivers screen, click Insert, then Multiple Driver Folder. Point nLite to the location where you extracted the slipstream drivers, such as C:\Drivers-temp\ and then click OK.
On the Select multiple drivers to integrate window you'll need to highlight the path at the top (such as C:\Drivers-temp\) by clicking on it once, then click OK.
On the Driver Integration Options window under Textmode integration options highlight the whole list by clicking once on the top item, then shift-clicking once on the bottom item. With that list still highlighted, click OK at the bottom.
Back on the Drivers screen, click Next. The Apply Changes: dialog should pop up, asking if you really want to start the process. Click Yes.
After the processing completes, you'll need to click "Next", at which point youâ'll be taken to the final screen.
On the "Bootable ISO" screen, change the "Mode" drop down menu from "Create Image" to "Direct Burn". Eject your WinXP disk, and insert a blank disk into your burner. For safety's sake, put a check mark next to "Verify".
Finally, click Burn.
Congratulations, you now have a proper install disk for any Toshiba laptop with S-ATA hdd(actually you can use it on any pc/laptop with S-ATA hdd).
Now you'll need to boot your laptop from that disk. In order to be able to boot from the CD, we'll first need to make a couple of quick changes in the notebooks BIOS. In the BIOS you need to make sure that the first boot device is the DVD-RW drive.
NOTE: Make sure to back up all your data before proceding, since the next step will erase everything.
Reboot the laptop with your new XP cd inserted, after it gets started, windows installer will ask you where you'd like to install Windows XP to: follow the prompts to delete all the current partitions, then follow the prompts to create a new partition, and install Windows XP to that. You can chose the "Quick Format" to speed things up.
Follow the rest of the prompts to windows in the usual fashion.
This solution was originally made for an another manufacturer notebook but I have just filled in where it regards Toshiba.

You will need the drivers for your systeme ready when XP finish installing, so make sure to download them before starting on all this, and make a CD so you can use them again. Most Intel chipsets has driver for XP on Intels homepage.
Regarding Atheros then you can find drivers here: http://www.atheros.cz/
Many of the drivers from Toshiba's Vista driver package will work on XP, just read the inf file or readme file.
If you have any questions then let me know.
