Make sure you have a new ofwboot.xcf. The old one booted to 0x640000. =20
Given that the kernel loads at 0x100000, that leaves 0x540000 free, which
is just over 5 MB.

The new ofwboot, version 1.8 or later, loads at 0xE00000, leaving 0xD00000=
=20
free, which is 13 MB, no? The change happened in the late Feb/early March=

time frame.

Take care,
