Denied { search } mingetty and can't log in

With kernel 2.6.15-1.1878_FC5, execmod checks are disabled, so I'm no
more getting the corresponding AVCs. Furthermore, I'm now able to start
in enforcing mode (the problem with mingetty was also solved). However,
from the audit.log file, I'm still getting denied read and search AVCs,
mainly due to irqbalance and hald:
