This is the reasoning behind the patch.

LINUX26_DIR is the basename of the directory containing linux
and this is currently always "linux-2.6.$(MAJOR).$(MINOR)"
MAJOR is always in the range of 20..30 at the moment
asn I believe it will be safe until linux-2.6.100.
If you believe otherwise we need to find another solution.

The script CAN be improved by only processing the 
"*linux-2.6.*.config" files in the first loop.

Only if you do not get any .config file in the second
loop, you revert to the old behaviour.

I know, this requires that the linux config is "well behaved"
I.E: called "*linux-2.6.*"
If you do "make linux26-update" to generate it, 
it should become "well-behaved".

The previous version would, if you selected kernel
and xxx-linux- and xxx-linux-2.6.28 existed,
use the latter, while the former is more appropriate.

As I see it, the goal is to use the config version
which is as close to the real version, but not 
of a higher version than the kernel.

Several board support packages does not implement
versioning, so you cannot do a lot about them
except hope for the second loop.

Feel free to improve as long as you meet the goal above.
