Notice that both stop after trying hpa f4000000.  I think this is probably
where the bug lies.  I did change the detection order between than and now.

No.  There's astk in the build-tools CVS module which will dissect that
stack dump for you and maybe show you what's really going on.

Don't do that then :-)

Yeah... i promised to fix this a while back; haven't got round to it yet.

I'm interested in debugging this one - I don't quite understand what's going on though.  You should see:

Found HIL at 0x%x, IRQ %d

then one of:

HIL: timed out, assuming no keyboard present.
HIL: no keyboard present.
HIL: keyboard found at id %d

which?
