Well, the PDA stuff took a bit longer to settle down than I would have =

hoped, but it seems fairly sound now.

I just committed the changes needed to make Xen happy with the PDA, =

which means making sure an appropriate GDT is set up early enough.

I also seem to have avoided most of the APIC issues under Xen by simply =

making the cpuid not report the presence of an APIC.

With these in place, things are getting fairly far, but not to =

usermode.  It often gets as far as trying to mount root, but it fails; I =

haven't investigated that yet.  But it also frequently crashes before =

then, depending on when it gets an interrupt.  I'm trying to work out =

what's happening here, but the symptom is eip =3D=3D 0x00000001 (!).

Chris, what local hacks do you have in your tree?
