You can ignore this ForceXPAon message, it was supposed to be a debug m=
essage
but was left with a normal print.

The 2.6.27 kernel does not have pci_ioremap_bar(), and compat.c defined=
 it
for older kernels as a couple of drivers (ipw, and some ralink driver)
make use of it. Can you try downloading today's version of compat-wirel=
ess and
then try to compile?

If you still see the complaint above then please ensure your kernel
headers are installed properly. By default this is the directory used:

/lib/modules/`uname -r`/build

So check:

ls -ld /lib/modules/`uname -r`/build

And ensure that's pointing to a 2.6.27 directory. Then check the includ=
e/linux/pci.h
file there and look for pci_ioremap_bar. If its there then I am surpris=
ed. Please report
back. I just tested a compile test against 2.6.27 on Ubuntu.
