Good idea! Geoff?

WoL support was introduced by

    [POWERPC] PS3: Gelic network driver Wake-on-LAN support
    
    Add Wake-on-LAN support to the PS3 Gelic network driver.
    Other OS WOL support was introduced in PS3 system firmware 2.20.


$ git name-rev --tags 3faac21546f5b213cda490d45fe5927d713e44f1

So you need 2.6.26 (or an earlier kernel with the appropriate PS3 patches, of
course).

You mean compile your own kernel from Geoff's sources?
Yes, that should work. And it's not non-reversible, if you install it next to
the current kernel.
