[XenPPC] 128 meg domU???

[Orran Y Krieger <okrieg@xxxxxxxxxx>]

Been trying to increase the memory used
for our library OS to 128Meg, 

In ppc970.c switched the rma size to
128 meg:
 

unsigned int cpu_default_rma_order_pages(void)
 {
-    return rma_orders[0].order
- PAGE_SHIFT;
+    return rma_orders[1].order
- PAGE_SHIFT;
 }

Also, modified the configuraiton
# Initial memory allocation (in megabytes)
for the new domain.
memory = 128

I got a series of hypervisor calls,
but console output no longer worked.  My assumption was that start_info
was moved, but as far as I can tell the memory location is hardcoded in
the domain builder. 
Got from amos a linux, and modified
its configuraiton the same way.  It hit a bug in Xen:

(XEN) BUG at mm.c:383

I also changed xen to have an rma of
64Meg (i.e., undid the change above) and changed just the configuraiton
file, and got the same BUG at mm.c:383

is there anything else needed to support
128 meg domu?
