Description of problem:
Installed RedHat 9 on Compaq Presario 2140US.  When booting the system hangs
during start of the pcmcia service.  There appears to be a problem  reassigning
the irq for the cardbus controller, and some other resource conflict.  If the
built-in ethernet is not started then the pcmcia service does not hang, but
doesn't recognize card presence or insertion either.

Syslog excerpt from starting pcmcia if ethernet was not started:




Version-Release number of selected component (if applicable):
kernel-2.4.20-18.9

How reproducible:
Always

Steps to Reproduce:
1.Install RH9 (any kernel up through 2.4.20-18.9) on Presario 2140US
2.Boot system
3.
    

Actual Results:  If ethernet cable is connected the system hangs during start of
pcmcia service just after "OK"
If ethernet cable is not connected system boots but pcmcia cards might as well
not exist.  There is no indication in log or otherwise that there are any cards.

Expected Results:  System boots normally regardless of ethernet connection.
pcmcia cards are seen and if supported they work normally.

Additional info:
I tried building a custom 2.4.20-18.9 kernel using redhat's 
kernel-source-2.4.20-18.9 starting with standard athlon config but turning on
ACPI features.  With this kernel power conserving use of the cpu happens (fan
actually cycles off!) and power-off at shutdown works, but the pcmcia issues
remain the same.
