That is what we use.

Did you use the snapgear CSR patch ?

	http://ftp.snapgear.org/pub/snapgear/src/snapgear-modules-20061012.sh

Do you do a make config and enable OCF and the appropriate modules ?

So are you now getting full performance or not ?

If not,  send me a copy these files and I should be able to sort it out.

	snapgear/linux-2.4.x/.config
	snapgear/modules/.config
	snapgear/config/.config

Cheers.
