Hi Will,

I have not used initramfs, usually qtopia and other large stuff (X.org / GTK ) is run
from jffs2 filesystem on flash, e.g rootfs is not in RAM but in flash.

Have you tried to adjust these kernel settings:
CONFIG_BLK_DEV_RAM=y
CONFIG_BLK_DEV_RAM_COUNT=1
CONFIG_BLK_DEV_RAM_SIZE=14000
CONFIG_BLK_DEV_RAM_BLOCKSIZE=1024

?

Regards,
Ivan
