Can't install Solaris 10 Express on my AMD64 Laptop!

Question

I was all excited to try out the latest and greatest Solaris OS and so I downloaded all the ISO's and burned them twice (made a mistake the first time around), and then rebooted my computer with the bios settings set to boot from CD.
At first it seemed to load the installer fine; but then again, I wouldn't really be able to tell since I'm a Pro Windows user, but a Noob in everything else. But it scrolled some very normal linux looking text on the left side of the screen and then gave me four options for how i wanted to install.
Here's where the problem occurs. Regardless of which choice I make the installation crashes and reboots (restarts) my laptop. I've searched the web, and these forums thoroughly looking for an adequate source of community support but it seems that there's not much of a community developed yet...and hence no one able to help me out.
So I have no idea what I'd need to do to get Solaris running. Frankly I don't care if it's running in 32bit or 64bit mode, as long as it runs.
My system:
AMD64 3400+ Mobility
2GB DDR Memory
ATi Mobility Radeo 9700 Pro w/128mb Ram
60GB Hard Drive (running at 7200 rpm)
DVD/CDRW Drive (writes @ 24x)
802.11g/b Build-in (Atheros chipset, Gigabyte distributor)
(3) Usb slots
Multi-format Card Reader
Infared Communicator (I don't care of this works or not)
S-Video In/Out
A/V Coax In/Out
Serial Port
Additional Monitor Port
Parallel Port
On-board 56k Modem (don't care if this works or not)
Firewire
VIA 8235 Onboard Sound (Realtek AC97')
VIA K8T400 Chipset-based Motherboard
I appreciate any help anyone can provide!
Regards, Abe

Nullvision,
Please accept my apologies for hyjacking your thread.
BTW: Assume the version to install is b72 for X86 !
(caused confusion with (!), it should have been:
Q to Nullvision: Assume the version you installed was b72 for X86 ? )
Richard,
Thanks for your reply. I was not looking for Athlon support, but indeed wanted to know if it works.
I'm aware that this Solaris Express is still a work (of art) in progress, but before asking Santa (= my wallet) for a new MoBo, I wanted to have this so called gray area demistyfied.
As you say, by default, solaris will boot/install 64 bit, regardless of the type of AMD64 processor used !
Therefore the bootstring earlier reported could have helped someone to get his machine booting, but is in a normal situation not needed by default.
So thanks to Sun and Santa, we might be running X86 64-bit Solaris next year. I started with S10 b48 in the beginning of this year on X86 32 bit, followed by Sparc 64. What will be the next step, Solaris on HP machines or AIX? We will see !
