Well.. keep in mind that that this particular machine has never run 
windows,
so I don't know if windows can reboot it either.

I expect it's like that long
laundry list of Dell servers that are in the quirks code - they all seem to
reboot via the bios when running in 32-bit mode.  I wonder what they
do when running in 64-bit mode (at least some of them are amd64 compatible).
