I tried add some options do kernel at boot:

root@slackade:~# dmesg | grep -i nvidia
Kernel command line: root=/dev/sda2 ro piapara=1 cga=1 nvidiafb:forceCRTC=0:bpp=16
nvidiafb 0000:01:00.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18
nvidiafb: Device ID: 10de0161 
nvidiafb: CRTC0 analog not found
nvidiafb: CRTC1 analog not found
nvidiafb: CRTC 1 is currently programmed for TV
nvidiafb: Using TV on CRTC 1
nvidiafb: Panel is TMDS
nvidiafb: MTRR set to ON
nvidiafb: Flat panel dithering disabled
nvidiafb: PCI nVidia NV16 framebuffer (64MB @ 0xD0000000)
root@slackade:~# 


didn't work...

I tried to pass driver parameters on kernel bootup runtime:

root@slackade:~# !dmes
dmesg | grep -i nvidia
Kernel command line: root=/dev/sda2 ro piapara=1 cga=1 highpclock=1 video=nvidiafb:forceCRTC=0,bpp=16
nvidiafb 0000:01:00.0: PCI INT A -> GSI 18 (level, low) -> IRQ 18
nvidiafb: Device ID: 10de0161 
nvidiafb: CRTC0 analog not found
nvidiafb: CRTC1 analog not found
nvidiafb: CRTC 1 is currently programmed for TV
nvidiafb: Forcing CRTCNumber 0 as specified
nvidiafb: Using TV on CRTC 0
nvidiafb: Panel is TMDS
nvidiafb: MTRR set to ON
nvidiafb: Flat panel dithering disabled
nvidiafb: PCI nVidia NV16 framebuffer (64MB @ 0xD0000000)

It didn't work.

I'd apreciate any help.

hm.  drivers/video/nvidia/ isn't exactly a hive of development activity
but let's switch this over to the mailing list and see if there's any
help.

Tnx!
