You can try enabling such drivers in the relevant l4linux_config_* in
linux/kernel-2.6.23-v2.  Normally, I do something like

mkdir ~/tmp/linux
cp l4linux_config ~/tmp/linux/.config
make ARCH=l4 SYSTEM=<i386|arm> O=~/tmp/linux menuconfig

and copy the resulting config back when I am done.

There are currently several restrictions on the DMA support in OK Linux.
First, it is currently only available for the IA-32 architecture.
Second, not all the APIs are implemented, but we have had good success
in running drivers for hardware which we've had to work with so far.

In any case, try enabling the driver and then rebuild.  Let us know 
how you go.
