Hi all,
It's been requested a few times here on the list, so I've posted an ip_wccp patch against kernel 2.6. It includes Henrik's latest version of ip_wccp.c which is linked from the Squid FAQ.

Note that this is only useful if you're building your kernel from scratch (from an SRPM, for example), and want to be able to configure it as any other module. If you are starting from an existing kernel and source tree, Henrik's make file is a better way to go.
It may also be worth noticing that the Linux IP/GRE module finally is getting WCCP support, so soon there won't be any need to patch the Linux kernel or use cludgy modules like ip_wccp in order to use WCCP.
Yes, I noticed the discussion of it on squid-dev. I've always patched my kernel ip_gre module with wccp support (it's just a few lines, and I figured I'd eventually run up against an edge case that ip_wccp couldn't handle--I haven't so far, but it could happen), but it is nice to see standard support.
However, using the ip_gre module is more complex than simply inserting ip_wccp, requiring actual configuration of a dummy gre interface. I've found it's easier just to use the decapsulating ip_wccp.
