I really disagree with this philosophy, although since you guys 
actually do the work I feel a bit funny arguing about it.  20ms isn't 
any big shakes but its worth meditating on for its general meaning.

A big bottleneck for starting up the machine is the HDD seek time, if 
by starting this thing up you had to go fetch it and touch the 
filesystem tables, etc, then that's delaying other things running in 
the background that could be using the HDD.

Its clear that if ISDN was up only on machines with ISDN hardware, 
that would be optimal.

Also, I keep getting a userspace package associated with ISDN 
installed, this is another case where some kind of virtual ISDN 
support package that includes the driver and userspace stuff could be 
installed on detection of the hardware, rather than crufting up the 
machines here which will never have ISDN.
