BIOS is pretty do-able on Ubuntu; I haven't yet tried PERC 5/i.

You won't have to - you can do it remotely.
describes the process for updating the BIOS. It's somewhat manual
right now. I started working on packaging firmware-tools and
firmware-addon-dell into debs, but there are a few gotchas dealing
with apt that we need to understand before unleashing it on people.

This isn't really a problem on the older system. I don't know if it's
firmware of a new driver that fixes this - it's been the list of
annoyances to fix for several years. It's only that - an annoying
message, not a functionality problem.
firmware-tools RPMs can now be used to update PERC firmware too, but
at this point you would have to use alien or somesuch to use them on
