I have to deal with lots of embedded / non-PC x86 based systems. Worst one
I encountered so far was a board where the VGA memory space was re-used
for an eeprom. The upcoming next generation hardware I'll have to support
is so far off-standard that I'll probably have to define a new platform
type (similar to OLPC or CE4100).

No, it is not all PC. Not anymore. Intel has started to sell into
the embedded space, where PC compatibility is not a requirement.
