Does this change also affect kernels for SLOF based systems (JS20, JS21,
Bimini/Powerstation, QS21, QS22)?
To avoid exactly that problem SLOF moved to a bit below 256MB on all
those platforms (about 220MB). There should be still enough space
between 64MB and 220MB to boot large kernels. It is, however, decreased
by 60MB.
