I reported an issue with later kernels with Xircom adapter not showing up
in /proc/pci and not functioning properly... I took the time to track it
down and have discovered the root cause of the problem ..

2.4.10 was working for me so I went back and conducted my experiments with
it .. I'm using PCMCIA 3.1.29 also.

with 2.4.10 with CONFIG_PM, CONFIG_ACPI and CONFIG_APM=m it doesn't work.
with 2.4.10 with CONFIG_PM, CONFIG_ACPI and no CONFIG_APM it doesn't
work.
with 2.4.10 with CONFIG_PM, CONFIG_ACPI off, and CONFIG_APM=m it does
work..

each time I rebuilt the pcmcia-cs package against the new kernel and
installed it ..

below are four files... lspci -xv -H1 and dmesg for the kernels with ACPI
and APM on... lspci -xv doesn't work it gives some can't read 64 bytes of
configuration space.

the same problem is there in 2.4.15-pre4 also ... I might go try and get
the results with 2.4.15-pre8 and pcmcia-16Nov if I get a chance..

Dave.
