You might also want to check out Jim Huston's patches at:

I don't think he did the ia64 part, but his base ia32 works very nice on 
2.5.73.  I believe Xavier & Jim had talked at one point about merging 
their effort, but I have no idea how far that got.  Now that 2.6-test is 
out, perhaps some consideration might be given to merging these patches 
back into the kdb sources?
