To make things simpler for distro people, I'm contemplating another patch
in this series, to allow something like:  pciehp_force=2

This would then *try* the ACPI BIOS calls, and only fall back to pcie_force=1
if the BIOS support fails.  This would be an ideal default for most desktop/notebook
distros to consider using.

Without this, they don't have any good choice:  use the defaults, and things fail
on the most popular brand of machines in the marketplace.  Use pciehp_force=1,
and they may break (?) on other brands.

So a hybrid of the two seems best.  Pity it couldn't be the default behaviour, though.
Or could it?  We're early enough in the 2.6.24 cycle for it..

Opinions?
