Does compile for me on 2.6.38-rc1 (after I avoid an compiler ICE
on the NOR flash driver by deselecting it, I don't blame the kernel
for that one tho):

Image Name:   Linux-2.6.38-rc1
Created:      Mon Jan 31 21:21:16 2011
Image Type:   ARM Linux Kernel Image (uncompressed)
Data Size:    4740192 Bytes = 4629.09 kB = 4.52 MB
Load Address: 0x60008000
Entry Point:  0x60008000
  Image arch/arm/boot/uImage is ready

Might this have something to do with it:

git log arch/arm/mach-vexpress/hotplug.c

    ARM: CPU hotplug: add Versatile Express hotplug CPU support

I don't know if it boots tho, if you pack up a Vexpress and
mail it to my place I promise I will make more than just
compiletests ;-)
