T43-W7 (new install) Fingerprint Software not interfacing with power-on password

Question

Went through a remarkably painless upgrade of my old T-43 to W7 yesterday.  After the W7 install, I added the Lenovo Toolkit, and let it load the recommended drivers/updates.  Then to regain use of the fingerprint function, I d/l'd the latest version of CSS, which seemed to install just fine (per upgrade recommendations, I uninstalled the fingerprints/power-on password prior to upgrade).  
In going through the enrollment process, the only checkboxes that appear above each "finger" are for Windows, not for the power-on password.  The power-on password isenabled and set in BIOS for both the computer and the hard drive (password identical to the Windows User password).  Tried with the Security Chip both Enabled and Disabled, and also tried "Clearing" the security Chip, to no avail. 
The result so far is that fingerprint login is working great for W7, but no longer works at all for power on, as it did under W2k.  I have an X301 that I upgraded from Vista to W7 on which all of this works perfectly, so I am pretty sure I know what should be possible, but maybe this is beyond the hardware function of W7 with the T43? Am I missing something?

Vince69,
Thank you again for your suggestion.  I tried updating the driver using the package you pointed to, and did not have any luck.  Kept getting "Driver not found", (and include subdirs was checked).  Also tried manually dropping into each subir in the file, and still no luck.
I came across an entry in http://social.technet.microsoft.com/Forums/en/w7itprohardware/thread/aa965e55-de21-4dd0-93e2-05e6d14... which seems to address the "Unkown Device" issue.  Go about halfway down the page, and the instructions provided by James Norman seemed to work for me--at least it made the error message go away.
But the original problem of the Fingerprint s/w interfacing with power-on password is still there.  After fixing the device driver problem, I reinstalled Fingerprint Software (I had uninstalled it before fixing the Device Driver issue), and I have the same behavior and selection choices under "Settings" as I had before--none of the settings include anything to do with power-on password.
Any more suggestions?
