Don't know.  I may just try frightening the thing with a kgdb session
one day....

I cannot recall seeing any tweaks like that in my bios but the BIOS on
the laptop I have (Toshiba Tecra 700CT) doesn't let you do much.  You
may be luckier.  There has to be some explanation for why we have this
bottleneck.

Yes.  This may be why cardbus is better to - on my laptop the cardbus
is attached to the PCI bus whereas the pcic is on ISA, viz:
