"BIOS people" are operating in a completely different culture.
Time to market, hardware workarounds, short-term
differentiators, secret bootstrap sequences and code compactness

strongly doubt that given the radically conflicting priorities a
reasonable dialogue can be established.
"BIOS people" control stuff like SMM mode. We can workaround some
BIOS problems, but definitely not all of them.
For servers, I guess Linux has enough of market share that we
could certify known-good servers (and maybe warn against
known-bad).
Server space is somewhat less of a problem BIOS quality wise: the
design cycles are longer, the features are more complex and the
profit margins are higher - which all results in saner practices and
more care. They even do server BIOS fixes for Linux.
The problem are the "Does it boot Windows? Ship it, forget it,
buldoze the factory" kind of desktop operations.
