It does indeed seem to be very problematic, and there are problems with 
the kernel itself that have been reported.  Unfortunately, preliminary 
analysis seem to imply that it is not just the BIOS, but the actual CPU 
which is causing some of these problems.

The EDD check is a different issue entirely, which might be possible to 
emulate.
