My experience, after trying this today: It worked fine here. What I did, on a 3.1-STABLE system (Compaq Proliant 3000), was: - Use the dg patched conf/Makefile.i386 conf/kernel.script include/pmap.h from 4.0-CURRENT. - Build new kernel, attempt to boot. Stops in loader with an error message I didn't write down, unfortunately. (But this was expected - dg's commit message explicitly mentioned the need for new boot blocks.) - Install boot1 boot2 loader from a 4.0-CURRENT system - these had been generated during a "make buildworld" on March first. And presto, it booted. Been running fine for 6 hours so far. The reason I wanted the larger KVA is that this machine has 576 MB memory, and I'm wondering if some unexplained hangs and reboots we've had could be due to the KVA size.
