Subject: [2.6.33-rc4] ACPI hitting kmalloc(MAX_ORDER) limits...

When booting 2.6.33-rc4 on an Ibase MI910 miniITX x86-64 mobo, ACPI
hits kmalloc MAX_ORDER limits [1] while parsing the AML; though a
warning, it is a regression over 2.6.32.

Would making the AML available help adding this to a testcase?

Thanks,
  Daniel
