apmd is power management, so turning that off is good, but you can kill that 
in you kernel too
isdn - unless you have ISDN hardware it's not doing anything
pcmcia - if it ain't a laptop buh-bye, but if it ain't a laptop you don't have 
it.
portmap - only used by NFS, no NFS mounts, you don't need
sendmail - augh, depends on what mode it runs, but if you kill it you won't 
get any reports
So, first 3 can be stripped from the kernel, then you don't have to worry even 
though they're hardware dependant. Latter 2 can be turned off, but if 
sendmail isn't running in daemon mode it's not hurting anything.

BTW - the implementation report dealie is coming along. Should be ready "Real 
Soon Now"
