The request_firmware() changes causing problems with make-kpkg

Using 2.6.26-git4 and -git6, and with CONFIG_FIRMWARE_IN_KERNEL=y,
make modules_install is calling firmware_install, which is dropping
files in /lib/firmware --- which make-kpkg is happily picking up and
including in the debian kernel package. Which was fine --- until I
tried to build and install kernel package for -git6, at which point I
got an error at install time because the second package was tying to
overwrite files installed by the first linux-image file. Doh!

Given that Ubuntu's firmware loader already tries to find firmware at
/lib/firmware/<kpkg> and only if that fails, to load it from
/lib/firmware, it seems like the obvious thing to do is to add a
quickie CONFIG option which changes the default setting of
INSTALL_FW_PATH in the top-level makefile from /lib/firwmare to

Maybe the userspace for other distributions won't support this, but
they can simply not use this CONFIG option for now; but it will solve
the problem for all Ubuntu, and possibly Debian, users who want to
build their own kernel using make-kpkg. If I cons a patch like this,
is there likely going to be any objections with it getting merged?
