[Linux-ia64] 2.5.45 with CONFIG_NUMA=y

Hi,

Booting the 2.5.45 kernel on our numa platform, we hit 2 problems:

. Current settings for DIG are : 512MB/bank, 16GB/node,(mmzone.h)  but our
platform can support 64 GB/node (Even with less memory, bios maps
each node memory modulo 64GB). 
As it has been cleanly coded :-), we just changed DIG_BANKSHIFT to 31 
(2GB banks) and system runs. 
Should these values bee incremented in the future ?

. We can't get X11 working (Xserver loops in user mode). Note that 
it works OK with 2.5.45 without DISCONTIG_MEM set. Having a look to the
mappings in /proc/ and the XFree86 log, we saw no difference. Any idea 
?

thanks in advance for your help.

Xavier
