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. Adrian
