OK, I've pushed a fix for the GK208 issue (an issue in unspilling predicates):

    gk110/ir: fix unspilling of predicates from registers

However the issue around thread sizes remains for all except the GK10x keplers.
On fermi we have 32K registers, on kepler+ we have 64K (not counting the
mythical GK210). So we have to tell the RA to restrict the number of registers
used based on thread size (or use 1024 as the number of threads when that
information is not provided).
