well two more bits of info in case someone knows what is going on:
1. X11 was built and installed from pkgsrc, and not from NetBSD base
system. Are there specific Xen patches in NetBSD X11 source tree??
2. The only interesting info in log file I see is
(II) LoadModule: "int10"
(II) Loading /opt/pkg/lib/xorg/modules//libint10.so
(II) Module int10: vendor="X.Org Foundation"
compiled for 1.6.5, module version = 1.0.0
ABI class: X.Org Video Driver, version 5.0
(II) VESA(0): initializing int10
(WW) VESA(0): remove MTRR a0000 - c0000
(WW) VESA(0): remove MTRR c0000 - 100000
(EE) VESA(0): V_BIOS address 0x0 out of range
(II) UnloadModule: "vesa"

(II) Unloading /opt/pkg/lib/xorg/modules//libint10.so
(II) UnloadModule: "vbe"
(II) Unloading /opt/pkg/lib/xorg/modules//libvbe.so
(EE) Screen(s) found, but none have a usable configuration.
Fatal server error:
no screens found
I'm not quite sure what to make of it...
