Matt brought up an excellent point, I'm curious though: are you able to boot to just a CLI instead of bringing up the whole WPS?
I ask because a large part of the drivers today, such as ACPI, HDD stuff (Dani and/or AHCI), maybe even some NIC stuff (MMRE comes to mind) is fairly generic in a sense that it supports a wide range of hardware. There are, and always will be execeptions to this, but in general you should be OK to at least get to CLI.
