This patch adds detection of broken 64-bit mode LL/SC on Cobalt units.
With this patch my Qube2700 boots a 64-bit build fine. The later units
have some problems with the Tulip driver.
Just out of curiosity, is there any practical interest in going 64bit on Cobalt besides the fun of it? One cannot possibly squeeze more than 4 Gb of RAM into a Cobalt box right? And doesn't 64 bit mode have costs of its own (doubled i-fetch bandwidth for starters)?
