Here's the response I got from SONY Canada regarding the brighness and
function keys on a Sony Vaio Laptop with Vista.

Thank you for contacting Sony Online Support.
Our VAIO computers are designed specifically to work with the Sony OEM
version of Windows with which they originally ship. Sony currently offers no
assistance, device drivers, support or troubleshooting for the installation,
configuration, or hardware compatibility issues for the beta version of
Microsoft's Windows Vista operating system. All technical support for the
pre-release Vista product is handled through Microsoft.
TIP: Microsoft advises all PC owners who plan to upgrade to their
Windows Vista operating system during the beta test "preview"
phase to visit:
http://www.microsoft.com/windowsvista
Once Microsoft has officially released their Windows Vista operating system
for retail sales, if your computer was labeled by Sony with the official
"Windows Vista Capable" logo, Sony may choose to provide limited basic device
drivers for the Windows Vista operating system for your model. Should any
updates be released for use on your model, a Windows Vista support link will
be available on your Model Specific support Website. However, if a Windows
Vista support link is not available, or active on your model specific site,
Sony has not released any updates to support Windows Vista for your model.
