The problem seems to be related to CONFIG_X86_PAE=n which results in
PAGETABLE_LEVELS == 2.

Not visible in -next due to "xen: remove support for non-PAE 32-bit",
but that is not in 2.6.26.

Thanks Adrian,

Bringing that patch over into .26 would be the easiest fix. It's effectively a bugfix because non-PAE Xen is broken and unusable anyway.

Alternatively, I can easily put a little patch together to use the right accessors that will compile in non-PAE.
