Issue building kernel driver

[Chris Holvenstot <cholvenstot@comcast.net>]

Although it may not be popular with the crowd here, I do have a valid
reason to run Windows - and I accomidate this using the VirtualBox
product.  

Since I try to be slightly useful and build as many of the "test" kernel
images I can I end up rebuilding the VirtualBox kernel driver (open
source) on an almost daily basis.

I attempted to rebuild the driver today and got the following error
messages running 2.6.24-rc1-git9

I got the same error with 2.6.24-rc1-git10.  Building this driver works
under 2.6.24-rc1-git4 (unfortunately due to some issues with my SATA
drives I did not get the chance to build git5-git8)

I am not sure if this should be reported to the kernel folks or the
VirtualBox folks - but the kernel code is what changed.  However I will
post this on the VirtualBox forum too.

Thanks
