pcmcia subsystem completely broken

[Michal Purzynski]

i've made some more experiments with that card and verious kernels, here are 
the results

kernel 2.6.12.6, so just before change, debian sarge, pcmcia-cs - results - 
card is beeing detected, firmware loaded and proper serial port found, i can 
connect via gprs. cool.

interesting pieces of dmesg from there

desipte this warnings, everything works as it should.

2.6.16, pcmciautils
with your change to serial_cs driver after plugging in card, i can hear one 
(low tone) beep, than nothing more - card seems to be "freezed", nothing gets 
detected, activity light just lightens up and stays so.
dmesg says

nothing more. just dead.

do you think it is memory ranges problem, serial_cs problem, or sth else ?
i really have to get it working. waiting for some answer from you.
