Network Interfaces take a while

[Anthony M Simonelli]

I've got a wireless pcmcia card for my laptop and am using ndiswrapper
for the driver.  I use network manager to connect to various wireless
access points.  When I boot the laptop, it hangs for about 30 at the
"configuring network interfaces" sequence of the boot.  I commented out
all of the interfaces in /etc/network/interfaces except for lo of
course, and when I boot, my laptop starts up super fast (but I have no
network interfaces once I log in).  It seems that it is timing out, but
how do I tell it not start at boot until network manager is running?
