This won't work for recent 2.6. kernels. Instead, you have two options:
a) (ugly) manually telling the kernel to use a new CIS:
# (as root)
# cat cis/IBMBT.dat > /sys/class/pcmcia_socket/pcmcia_socket0/cis
b) (preferred) patching the kernel to handle the case correctly.
Add a line to drivers/serial/serial_cs.c:serial_ids[] containing
PCMCIA_DEVICE_CIS_MANF_CARD(0x0105, 0x4254, "cis/IBMBT.cis")
rename IBMBT.dat to IBMBT.cis in the /lib/firmware/cis directory and submit
a patch adding cis/IBMBT.cis and the line to drivers/serial/serial_cs.c for
inclusion into the Linux kernel.
Best,
Dominik
