[PATCH] 2.6.8.1 platform update for ES7000

[Davis, Jason]

Hi -

This update only applies to Unisys' ES7000 server machines. The patch
adds a OEM id check to verify the current machine running is actually a
Unisys type box before executing the Unisys OEM parser routine. It also
increases the MAX_MP_BUSSES definition from 32 to 256. On the ES7000s,
bus ID numbering can range from 0 to 255. Without the patch, the system
panics if booted with acpi=off.
This patch has been tested and verified on an authentic ES7000 machine.

Thanks,
Jason Davis
