I know this is too late for you but...

Looks like kasprintf was first added to the kernel in 2.6.18, not
prior to 2.6.12 like DAHDI currently believes.  The following
command on a checkout of the current trunk of DAHDI should allow you
to build against the 2.6.17 kernel.

  $ curl "https://github.com/sruffell/dahdi-linux/commit/cbd536aea83.patch" | patch -p1

I cannot commit it to trunk yet though because I know that there are
some distros which have that command back ported (OpenSUSE 2.6.16
comes to mind) so those will need to be checked out.

Cheers,
Shaun
