Yeah, I wonder whether the correct fix is to put into the Makefile:
  KVER ?= $(shell uname -r)
so that it is setable from outside:
  $ KVER=foobar make
or instead to provide an executable "uname" in Scratchbox which returns:
  $ uname -r
  2.6.21-omap1

Yeah, although the "/lib/modules/current/build" and "/lib/modules/current/
source" links don't exist yet. Or are they in some source package?

Also, the tree "/lib/modules/2.6.21-omap1/" looks weird in this way: The 
kernel module executable images are at toplevel without any 
subdirectories (even without the "kernel/" subdirectory). Was that 
intended?

cheers,
