I seem to have narroved the problem down to the function direct_remap_area_pages() which fails on an MMU update.

Xen tells me about this, in:

(XEN) (file=/mnt/hda3/home/jacobg/xeno-unstable.bk/xen/include/asm/mm.h, line=157) Error pfn 0003ff40: ed=fc599260, sd=fc5996a0, caf=80000002, taf=f0000001

The offending hypercall is at arch/xen/i386/mm/ioremap.c around line 437.

A couple of variables that may be important: start_address is 0xf8880000, and address-start_address is 0x2000.

Changing the amount of dom0_mem does not seem to help. The closed-source ATI flgrx driver is not involved at this point, though I am sure it has some problems as well, the wrapper has a lot of references to virt_to_phys().
