Hi, I get the blank screen of death loading up Knoppix unless I enter "knoppix xmodule=vesa" at the boot line. With that cheat code, my copy of knoppix loads up fine.

My graphics card is:
BFG Tech BFGR73256GSOCE Geforce 7300GS GDDR2 PCI Express x16 Video Card 512MB supported (256 on board)

The output from lspci -v is:
