New Card and System freeze at 'modprobe hostap_cs' when two pc cards inserted

I would like to report a new supported card:

Host AP version: Prism2-2002-05-19
Linux Version: Red Hat 7.3
Kernel: 2.4.18-3
Product name: Buffalo WLI-CF-S11G CF wireless lan card ( 802.11b) using Intersil 2.5 chip set
hostap_cs.conf entry:
card "Buffalo WLI-CF-S11G"
  version "BUFFALO", "WLI-CF-S11G"
# manfid 0x026f, 0x030b
  bind "hostap_cs"
cardctl indent:
product info: "BUFFALO", "WLI-CF-S11G", "", "" manfid: 0x026f, 0x030b
function: 6 (network)

Prism2-2002-05-19 installed fine on my RedHat 7.3 ( 2.4.18-3 ) system using a Buffalo ( Melco ) card with the Prism 2.5 chip. I configured wlan0, ran dhcpd on the same machine, and my Windows XP client was able to connect without any obvious errors.

BTW, Buffalo is a consumer oriented brand of Melco, which is an OEM partner of Intersil.

I have not tested yet for minor gliches or problems under heavy loads etc.

HOWEVER This is most likely a PCMCIA issue rather than a Host AP issue, so it may be off topic, but I would be greatful for some pointers if anyone has them.

If a serial pcmcia card is inserted in the other PCMCIA slot before boot, the system freezes at the point where it does 'modprobe hostap_cs' ( no problems up to that point, serial card is in slot 0 and recognised first, no PCMCIA or cardctl errors in /var/log/messages ). If the same serial card is inserted after boot ( followed by # cardctl insert 0 ) the system freezes with no errors. Again, this is probably a problem with my PCMCIA configurations, but any information would be much appreciated.
