I just updated my PowerMac G5 to the latest Debian SID, and graphics
didn't work.
I noticed that Debian's config file for vmlinux-6.12.38+deb13-powerpc64
doesn't include entries that I have had to add for a while now to enable
my NVIDIA GeForce FX 5200 video card on my PowerMac G5:
CONFIG_FB_NVIDIA=y
CONFIG_FB_NVIDIA_I2C=y
CONFIG_FB_NVIDIA_BACKLIGHT=y
The NVIDIA GeForce FX 5200 card was an entry-level graphics card for ADC
displays on PowerMac G5 (and G4?) systems. After reverting to a custom
kernel (vmlinux-6.13.6) that was compiled a few months ago with the
above options, graphics works. I haven't checked whether the FX 5200
card works using the above CONFIG_FB_NVIDIA options with the latest
kernel, but it should.
Hope that helps.
