Booting with noapic works.

 Hmm, that's quite odd.  There's some recent work in this area in
linux-next -- do you have means to try that tree instead?  Did any older
version of Linux work on this board?

 Either way, please send .config and a full log from a bootstrap with the
"noapic" option -- while this piece of code is not reached in such a
scenario, various configuration tables will be dumped at the beginning
regardless and that may give us hints.
