Hrm... Interesting. It dies reading from the chip (MMIO). Can you
check with xmon "h" command if there's a translation for 0xd9000000 ?

I'll do that at my next reboot.

(Or hack radeonfb init to printk the result of ioremap of the registers
to see if it's really 0xd9000000 or if the structure was corrupted some
way)

I'll try to find where is the init.

What is the exact error in xmon ? (vector number)

Vector 200

Ah, that's a machine check... interesting. So either the address above
is bogus, or the card is crashed. In this later case, noaccel should
have helped, except if, for some reason, the argument was ignored
when setting the initial mode...
