Yes, it says what address the frame buffer is mapped into & what i/o
port it is using for register access. Neither of those is terribly
useful for figuring out why it doesn't want to start the server.
Darn. I should have thought about this sooner.... About 1 year ago,
when we were first getting X working, I used one of the ATI Mach64
cards that shipped in some older AS200s. This was a borrowed card. I
wrote the following about it in private email after getting it working:

I don't know if xf86ReadBIOS was ever fixed. But you might want to
try specifying the clock chip & ramdac. I no longer recall what I
meant by "bludgeon the driver into submission" & I no longer have that
copy of the X server code. I do still have the xf86 config file where
I said:
Section "Device"
Identifier "m64"
ClockChip "ics2595"
Ramdac "stg1702"
Option "override_bios"
Option "no_block_write"
Option "no_bios_clocks"
# Clocks 135.0 80.0 40.0
EndSection
These are almost certainly wrong for your spiffy new card, but you get
an idea of what I needed to inform the X server about.
