Bug 27362 - ThinkPad Fn key types NULs into the console

Hi,

I hope it's appropriate to advertise my kernel bug here to get some
traction...

In short: under vanilla 2.6.37, the Fn key of my ThinkPad R50e is active
on the console: it adds NUL characters to the input stream on each
release.  This happens without any userspace involvement, at the very
start of the initramfs phase of bootup (after break=top for those using
initramfs-tools):

(initramfs) cat
^@

At this stage no modules are loaded (my .config and dmesg is linked from
https://bugzilla.kernel.org/show_bug.cgi?id=27362).  Showkey prints
0x00 0x81 0x8f 0x00 0x81 0x8f on release of the Fn key (with autorepeat).

These NUL characters constitute a bug in my opinion.  Please let me know
if I can help finding the cause.
