Well, this list has David Hinds, myself, Dominik Brodowski and a few
other developers on, which are what you could call "the most active
Linux kernel PCMCIA people" so by that it is the most appropriate
place to ask.
That said, I have other commitments which don't allow me to work full
time on PCMCIA, and Dominik does other stuff as well, so there's little
chance for us to do a deep investigation.
What we really need are more good kernel developers in PCMCIA land who
are willing to look into issues like this - I do suspect that, where
they occur on the x86 architecture, they may be related to other areas
which I certainly have a lack of knowledge (eg, ACPI or BIOS quirks)
since I'm not an x86 guy.
