UPDATE - Problem solved
Forgot to pound out Load "dri" and rename the card from NVIDIA GeForce 4 (generic) to
NVIDIA GeForce 4 440 Go.
Upon doing that and rebooting, I got an NVIDIA logo page when XFree started, and now the graphics are True Color.
Simply wonderful, and simply not doable without the help of the fine participants of this forum!
Thanks a ton!
PS: does anyone know where I can find a Broadcom 43XX driver for my wireless card?
