Many people don't trim it down enough and end up with strange problems,
looks as if you did a good trim job though I really doubt your need
for *_MAX=128 and SHMMAXPGS=512.

I also thought you had an NCR scsi controller, which means you don't
need BOUNCE_BUFFERS.

Do you _really_ need these?

The default is 1024, you trimming this on purpose?

Unless you are really using QUOTA's remove it.

Hummmm PCI machine with NCR scsi controller, nope you do not need this,
remove it!
