When you apply these patches, are there any errors? because these patch 
will only work with current CVS (release on 10th of Aug 2005)

I assume the error is " Makefile:216: *** commands commence before first 
target. stop"
This looks like the vendor_xilinx.diff or uClinux-dist.diff did not 
patch properly. any error while you apply these patches?

Did you download the cvs before you apply the patches? or after you 
apply the patches?
Maybe you should try clean download of uClinux-dist before you apply the 
patches.
If you still having the same problem after you clean download of 
uClinux-dis, could you please send me a copy of your Makefile (locate 
under uClinux-dist/vendors/Xilinx/uclinux-auto folder)

As long as you install the board support package (BSP), I believe the 
instructions should be pretty much the same.
