There are 2 possible solutions to this:

1) Set your GVP hard disk to automatically add a minimum number
of buffers when it fire up; 5 would be about right.  Then
add the rest of the buffers via your startup-sequence (Addbuffers).

2) or you could use 2 partitions anyway :-)

Nope; you want to keep the filesystem buffers out of C00000 ram as well.
(and you can do it via step 1)
