[Smaug] X running slow?

[Meg McRoberts]

Here's the VGA bit from lspci:

01:00.0 VGA compatible controller: VIA Technologies, Inc.: Unknown device 3108 (rev 01)

Should I care that this (and several other devices) are
"unknown device"?  ;-)

What next?  Or is there something I should read to figure
it out myself?

Thanks much!
