There's no such thing.

I'm not aware of any such released version, so this must be a test build
or similar.

Since this is a new device, support in 2.6.36 will likely not be
possible. You might be able to modify iwl-6000.c to load a v5 firmware
(set IWL6000G2_UCODE_API_MAX to 5) but we cannot support that and I
don't know that the firmware API didn't change and you'll run into
crashes again.

I believe that the only supported way to get your device working is to
start with 2.6.37 and the latest official -5 firmware image from the
Intel download page.

If you're really stuck on 2.6.36 for some reason, you can use
compat-wireless to backport the driver.
