I just tried to recompile the netbsd 2.0.2 kernel with

options DMAXSIZ="3221225472U"

The result is kernel panic on boot: it says error 8 executing /sbin/init
(if this is errno, then it means ENOEXEC (=exec format error).

OK, I have a machine with large amount of RAM and a data-intensive
application that really could use 3G of RAM, but the data seg rlimit is
limited to DMAXSIZ which is 1G! I get the same panic trying to recompile
with DMAXSIZ set to 2G.

Any suggestions how to increase data seg size?
