Hmm

Well downgrading the kernel was partly successful - i.e. I got back to version 
2.6.22.5-31, installed the sources and re-installed the NVidia driver.  I 
then managed to install the NVidia driver against the default kernel.

I then managed to install the kernel-rt package, and once again booted into 
text mode.

Sadly, installing the NVidia module once again failed - basically the same 
message as with 10.2

ERROR: The kernel header file
  '/lib/modules/2.6.22.5-31-rt/build/include/linux/version.h' does not
  exist.  The most likely reason for this is that the kernel source files
  in '/lib/modules/2.6.22.5-18-rt/build' have not been configured.

I've done some digging:

/lib/modules/2.6.22.5-31-rt/build is a symlink to 
                 /usr/src/linux-2.6.22.5-31-obj/x86_64/rt

This directory contains only a single file called Module.symvers (matching 
kernel-rt and kernel-source installed.

I've gone back to the updated kernel, and successfully re-installed the NVidia 
driver - so I evidently have correctly configured sources.  Looking at
/usr/src/linux-2.6.22.5-31-obj/x86_64, there are directories for default, xen 
and debug, and they each contain version.h - but there is no rt/ folder.

I'm not a coder, so all I have to go on is logic - but it appears to me that 
the kernel-source package does not include the necessary files for a realtime 
kernel.

Is there any way that these files can be generated without rebuilding the 
kernel?
