I just built and installed NetBSD-current/i386 with XFree 4.5.0:

Looks like all works just fine as prior but i found quite weird behaviour of 
X. Ok, at least weird from my point of view. When i run X in any way, for 
example as above, it asks SSH password. Twice. And starts X only when i enter 
valid password for my login.

Just wondering how to disable this feature so i can start X without extra 
password checks as in old good pre-PAM days :)

PS: Of course i installed new kernel first, rebooted, installed userland, 
updated /dev, run /etc/postinstall fix and so on.
