15 PowerSurge Architecture - tested on UMAX s900, Apple 9600
16 The second processor on this machine boots up just fine and
17 enters its idle loop. Hopefully a completely working SMP kernel
18 on this machine will be done shortly.
19
20 The code makes the assumption of only two processors. The changes
21 necessary to work with any number would not be overly difficult but
22 I don't have any machines with >2 processors so it's not high on my
23 list of priorities. If anyone else would like do to the work email
24 me and I can point out the places that need changed. If you have >2
25 processors and don't want to add support yourself let me know and I
26 can take a look into it.

28 BeBox
29 BeBox support hasn't been added to the 2.1.X kernels from 2.0.X
30 but work is being done and SMP support for BeBox is in the works.
31
32 CHRP
33 CHRP SMP works and is fairly solid. It's been tested on the IBM F50
34 with 4 processors for quite some time now.
