The ICAP driver should be in the uClinux sources, although I'm not sure
when Xilinx's snapshot was taken to generate the VMWare images.

A couple of things - you want to use the --dry-run option to patch first
time through - as the name suggests it doesn't actually change anything,
just tests the water.

Also ,you will probably want -p0,  so

patch -p0 --dry-run < icap.diff

from uClinux-2.4.x directory is probably the way to go.

Once it looks clean, then do it again without --dry-run.

Regards,

John
