Still no Apple 17" LCD(ADC) support?

[Stephen J. Sanders]

It would be nice to hear from someone who is actually using an
Apple 17" LCD and getting more than 8 bit color depth in linux. (It
was possible to get 8bit color depth in YDL 2.1 using a video card with an
ADC connector.)  With the setup that I described in my previous message
and reproduce below, the screen goes black immediately after I issue
the boot command.  If I look at /var/log/messages, the lines that look
like they might be relevant don't seem to indicate a problem:

Kernel command line: root=/dev/hda10 video=radeon:dfp

262144k highmem)

Console: switching to colour frame buffer device 160x64
radeonfb: ATI Radeon QD  DDR SGRAM 32 MB
radeonfb: CRT port no monitor connected

My best guess is that somehow I managed to get a non-standard radeon card
that is not supported, or that only pci bus cards are supported (I have an
AGP card).
