now that's the smart idea. having some ready 64bit xen-3.1 binaries, i've tried
it, worked. well, almost. now i have 64b xen, 32b dom0, 32b userland of course.
and - two questions are comming with it:

1. how do i compile xen 64b on 32b system? XEN_TARGET_ARCH=x86_64 fails while
compilling.

2. after booting 32b dom0 under a 64b xen i can see 'total memory -757870',
'free_memory 0' in xm info. (with dom0_mem=512M, and totaly 3 GB of ram in this
machine, what xen itself can see -> xm dmesg shows it).

so now way i can boot any kind of domU.

now what about it?

btw - 32b xen 32 bit dom0 -> same amount of memory, below zero.
