There are a few solutions and most revolve around using the file
wireless_copy.h from the wpa_supplicant tarball. This is the approach used by
Debian with older linux headers and it works fine.

1) Store wireless_copy.h in the files directory, patch wlan.c to use it
instead, and copy it over during src_unpack. The problem is that
wireless_copy.h is 44K and the guidelines prefer nothing above 20K.

2) Have the ebuild download the wpa_supplicant package and copy it out from
there.

3) Wait for a newer version of linux-headers to be marked stable.

Created an attachment (id=93675) [details]
files/hwinfo-13.0-linux-headers-fix.patch

This patch depends on wireless_copy.h from package wpa_supplicant being copied
to the src/hd/ directory.

deps fixed - to indicate that 2.6.17 headers should be used.
