I would _highly_ suggest learning how to make a custom kernel.  There's
quite a number of things that can be pulled out of the kernel if you're
never going to use them.  (SCSI for example) And a smaller kernel takes u=
p
less resources on the system.  I have a custom kernel in my Qube2 that is
running simh and has been running for quite some time.  (Though I suppose
that's a bad example because I just tried to ssh to it and it's down. ^_^
Have to really get my X10 control stuff working again...)

Anyway the custom kernel thing is not that hard to do and really can make
a difference.  Just make sure your serial console is working properly for
that inevitable time when you screw up and have a kernel that won't boot.=
