I have a T1000 with which I could try to reproduce Riccardo's issues.
Hardware wise they should be pretty similar. As the T1000 doesn't have a
CDROM, I'll try to netboot a few newer kernels and report my findings.
Will take me until next week though, as the machine is in (cold) storage
now.

@Adrian:
Aren't there some build servers using UltraSPARC T2 or T2+? Do they run
with the latest kernels?
