MD driver on physical ram? (64MB cachable problem)

Hi All,

Would it be possible to use the 'md' driver on a physical address?
I'm particularly interested if someone has some hacks or custom
patches that would allow this.

The problem I have on some old hardware is that the chipset can
only cache the first 64MB in L2, but the machine has 128MB total.
I'd like to limit the memory with MAXMEM=64M, and then mount
the remaining memory as a very fast swap drive.

Thanks in advance for any ideas.

Peter.
