Sun could fix that, but would you really want a replacement for BIOS?

Yes, I really would. I also have a hard time believing BIOS is the
issue. I have a 7110 sitting directly below an x4240 in one of my
racks... the 7110 has no issues reporting disks properly.
BIOS is indeed an issue. In many x86/x64 PC architecture designs, and
the current enumeration design of Solaris,
if you add controller cards, or move a controller card, after a previous
OS installation, then the controller numbers
and ordering changes on all the devices. ZFS apparently does not care,
but UFS would, since bios designates a specific
disk to boot from, and the OS would have a specific boot path including
a controller number such as
/dev/dsk/c3t4d0s0 that could change, hence no longer boot.
Getting to EFI firmware, dumping BIOS, and redesigning the Solaris
device enumeration framework would
make things a little more flexible in that type of scenario.
