You probably already figured all these out, but just in case...

Adding mem=8M to kernel cmdline should do it.

See Makefile.boot in mach-omap1 directory.

You can set a mapping in .lds file. See the old Psion second stage
bootloader boot2nd at:
http://www.yipton.demon.co.uk/boot2nd/latest/boot2nd.tgz
The file you want to look is boot2nd.lds.

Tony
