I've seen no option to choose a kernel for live usage of
KXStudio_10.04.2-LiveDVD_64bit.
The default kernel is a generic kernel.

ubuntu at ubuntu:/etc/X11$ uname -a
Linux ubuntu 2.6.32-21-generic #32-Ubuntu SMP Fri Apr 16 08:09:38 UTC
2010 x86_64 GNU/Linux

Apart from that, which file gives information about the used driver?

TIA Ralf
