However if you set the broadcast explicitly, it will take it.
[root at test1 root]# ifconfig eth0:1 131.194.131.27 netmask 255.255.192.0
broadcast 131.194.191.255
eth0:1 Link encap:Ethernet HWaddr 00:30:84:3E:96:59
inet addr:131.194.131.27 Bcast:131.194.191.255 Mask:255.255.192.0
BTW this also does this on my 7.3 laptop.
