Mainline kernel source curiosity

[Curt Howland <Howland@Priss.com>]

Hi. Up to date Squeeze, compiling the latest 2.6.36-rc4 kernel.

Last time the problem was compiling the kernel at all, which is
working just fine now thank you Debian-User.

fakeroot make-kpkg --append-to-version -curt1.0 --initrd kernel_image

creates the .deb file just fine, it installs fine, but when I run it
and try to get the VirtualBox and Nvidia drivers to compile, this is
what I get:

from vbox-installer.log

==========
Makefile:170: *** Error: /usr/src/linux (version 2.6.36-rc4) does not
match the current kernel (version 2.6.36-rc4-curt1.0).  Stop.
==========

The thing is, there is no such error with 2.6.35.4-curt1.0, nor when
it was 35-rc4-curt1.0.

So why would it be choking on the custom extension now? I used
_exactly_ the same compile command, listed above.

Which I guess means I have to wait for Nvidia to fix a signed vs
unsigned change in the kernel source.

Can folks suggest if it would be worth while reporting this to Nvidia?
