The whitelist could always be modified.

It's completely possible that the HP has miniPCI, which would then be
behind the SB600. But it's a little stupid not to have miniPCIe when
the RS690 does support it.

Sure, BIOS can fail at setting up decoding and bridges or the kernel
can fail at following the setup.

The BIOS can of course also do this selectively and/or on purpose,
e.g. I could expect that if a wlan card is not in the whitelist.

This platform (RS690+SB600) is supported by coreboot. It would make a
nice exercise for anyone interested in firmware development to create
a coreboot port for his machine. (It's still a bit of work though.)
