I do not agree with this at all.  I have run dozens of U1's with 64-bit
Sol 7 (happily editing boot.conf) and had *no* trouble whatsoever.
Basenji.com is currently a U1/170E running 64-bit, and it runs great.
My biggest threat to stability is the power in CA. 

As for the U2's, remember that models 1170, 2170, 1200, and 2200 all have
ULTRASPARC-1 CPU's, and they seem fine as well. (Basenji.com is due for an
upgrade to a 2200 very soon).  I know of a 2200 running as a webserver on
a T3 that gets pounded like mad, last uptime (before service) was 218
days... It's running 64-bit....

Just my $0.02 worth.
