I had a friend help me, but I believe the jist of it was.

I didn't have PCMCIA complied into the kernel (it used to be an external
ebuild, but now it's IN the 2.6.15 kernel)

daevid linux # grep PCMCIA .config 
# Bus options (PCI, PCMCIA, EISA, MCA, ISA)
# PCCARD (PCMCIA/CardBus) support
# CONFIG_PCMCIA_DEBUG is not set
CONFIG_PCMCIA=y
CONFIG_PCMCIA_LOAD_CIS=y
CONFIG_PCMCIA_IOCTL=y
# PCMCIA SCSI adapter support
# CONFIG_PCMCIA_AHA152X is not set
# CONFIG_PCMCIA_FDOMAIN is not set
# CONFIG_PCMCIA_NINJA_SCSI is not set
# CONFIG_PCMCIA_QLOGIC is not set
# CONFIG_PCMCIA_SYM53C500 is not set
# CONFIG_PCMCIA_WAVELAN is not set
# CONFIG_PCMCIA_NETWAVE is not set
# CONFIG_PCMCIA_RAYCS is not set
# CONFIG_PCMCIA_HERMES is not set
# CONFIG_PCMCIA_SPECTRUM is not set
# CONFIG_PCMCIA_WL3501 is not set
# PCMCIA network device support
# CONFIG_NET_PCMCIA is not set
# PCMCIA character devices
# PCMCIA devices

I think I did have to get some new updated PCMCIA tools. 
"esearch pcmcia" should get you in the ballpark.

These are what I have installed. Don't know if I still need the bottom two
anymore?

I also didn't have host_ap complied properly:

daevid linux # grep HOST .config
CONFIG_HOSTAP=y
# CONFIG_HOSTAP_FIRMWARE is not set
CONFIG_HOSTAP_PLX=y
CONFIG_HOSTAP_PCI=y
CONFIG_HOSTAP_CS=m

I also think I had to make a udev rule:

daevid rules.d # cat /etc/udev/rules.d/10-wireless.rules 
KERNEL="eth*", SYSFS{address}="00:02:6f:x1:y2:z3", NAME="wlan0"

It's kinda irritating that you end up with all these extra network
interfaces that are all the same :( 

daevid rules.d # iwconfig
eth0      no wireless extensions.

eth1      no wireless extensions.

lo        no wireless extensions.

That's all I can recall at the moment. I hope that helps you.
