The problem is specific to !CONFIG_HIGH_RES_TIMERS.  This seems to fix
it (untested):

No good, this double faults on boot.  I'm trying to work around it by
compiling with high res timers even though I don't have the hardware to
support them.

Does not with with high res timers enabled either - it boots halfway
then I just get endless screenfuls of "============================".

Can anyone reproduce the failure to build or boot 2.6.14-rt13 with my
config?

OK I tracked this down.  It works as long as CONFIG_KTIME_SCALAR is on.
I tried -rt6 and -rt13 with various combinations of preemption levels
and debugging options and all configs with this unset failed to build or
boot.
