You have a memory overlap (your other message confirms it).  The driver 
that expects to access registers deals with RAM instead.  All messages are

That's a separate problem.  See "Processor type and features" -> "High 
Memory Support" in the kernel configuration, or just remove 
CONFIG_NOHIGHMEM=y from .config and run "make oldconfig".

It cannot fix the 896MB/1024MB issue, but it expected it to fix the PCMCIA 
problems.  Apparently it doesn't.

"lspci -v" used to show "Memory at 3f6fb000".  I believe that area has 
shifted elsewhere because 0x3f700000-0x40000000 is now marked as reserved 
(which is a good thing).

Please post the output of "lspci -v" for the bridge again, after booting 
with --no-mem-option and 1Gb of memory.

Also please post the contents of /proc/iomem (you posted /proc/meminfo).
