Since I cannot look it up at command line, I had to look it up via
Google.
It seems to be a "NVIDIA GeForce2 MX graphics processor with AGP 2X
support" as per
http://www.everymac.com/systems/apple/imac/specs/imac_700_fp.html
Alright, that explains the colour problems - there's no driver for this
chip in 6.x and OpenFirmware calls set only palette registers for the
analog output, I guess the iMac G4's panel uses the digital one.
Any chance you could try a -current or 7.x kernel? I wrote a driver for
the 2MX ( gffb ) a while ago and also added a workaround for the
palette problem to genfb.
have fun
