That links to a discussion on keyboards... But I did find the cross compilers in the howto you mentioned. So thank you!
Why putting "cross-compiler" and "cross compiler" in the search box doesn't lead there I don't know.
On closer look, it doesn't seem that I need the 2.6 kernel to get IPSEC running, just something called KLIPS (Kernel Level IPSec, I think). I wonder how hard that'll be. Not being an actual kernel hacker, I think I'll leave the porting to people who know what they're doing.
