Have you try the exact values I suggested? 0xea010000 is a very
different location than 0x0e000000, which you were using.

For reference, the "reserve=start_location,size" boot option is for
reserving a contiguous "size" block of memory, starting at
"start_location". As far as I can tell, the range you were reserving
would have been consumed by the AGP (ie. they both had the same start
address). The start location and size of the AGP aperture is set by
BIOS. PCI memory space is allocated afterwards, usually from a
location somewhere after the end of the AGP block.

According to dmesg, you reserved from 0x0e000000 to 0x0fffffff
inclusive. If you look at the /proc/iomem you posted (either one),
you'll notice the big jump in memory addresses between "Kernel data"
and "ACPI Non-volatile Storage". In the middle of this region is where
you reserved memory.

Somebody correct me if I'm wrong, but that's my understanding of things tho.
