Trying to debug the cdrom issue, I see

   Compiling whole program out/ccode32.o
src/util.c: In function =E2=80=98__end_thread=E2=80=99:
src/util.c:183: internal compiler error: in simplify_subreg, at=20
simplify-rtx.c:5055

(with F12's gcc (GCC) 4.4.2 20091027 (Red Hat 4.4.2-7))

The issue seems to be with the pos variable; removing everything except=20
the declaration + initialization retains the error, converting the=20
variable to static removes it.  Presumably you've seen many of these?

With that out of the way, I get:

   Linking (no relocs) out/rom32.o
   Linking (no relocs) out/rom16.o
   Linking out/rom.o
`cdemu_drive' referenced in section `.text32' of out/rom32.o: defined in=20
discarded section `.discard.var16.src/cdrom.c.107' of out/rom32.o
`cdemu_drive' referenced in section `.text32' of out/rom32.o: defined in=20

`cdemu_drive' referenced in section `.text32' of out/rom32.o: defined in=20
discarded section `.discard.var16.src/cdrom.c.107' of out/rom32.o

Given we're chasing a cdom related problem, this is suspicious, even=20
though we aren't using cdemu.  Presumably access to uninitialized memory=20
can confuse disk.c.

out/rom32.o: In function `check_irqs32':
/build/home/tlv/akivity/qemu-kvm/roms/seabios/src/util.c:109: undefined=20
reference to `trampoline_checkirqs'

No idea where that came from.
