RE: multiple devices behind a cardbus bridge (adding magma pci extender support)

["Mark Krischer" <mkrisch@cisco.com>]

i believe it's the former.  though i'm still tracing through the code.  it
looks like the new yenta.c is what's used now?  i had to return my magma pci
extender and won't be getting new ones until the end of next week.  so i
guess i'm trying to get an idea of where i should start playing when i start
next week.

my understanding was not so much that i needed the hot-plug specific stuff,
but rather whatever new pci support you've added.  but i could be on the
wrong path here.

thanks.
