[I've been offline for a week due to using bad memory while trying to 
flash a BIOS.  Naturally it crashed, and I couldn't boot my main 
machine.  I ended up ordering a pre-flashed BIOS chip from two states a 
way... and waiting the few days for it to ship.  I feel like I'm just 
back from the dead! =:^)  ]

Hmm... perhaps it's elsewhere in the 2.6.26 kernel config.  I'm now 
running 2.6.31, and will be starting on the 2.6.32 rcs in a week or two...

It's also possible it's turned off and not even available to you due to 
some other dependency.  I'd try tracing it if I hadn't just fallen a week 
behind, just to see.  You can grep "PROC__PAGE_MONITOR" in the kernel 
sources and see what comes up if you want.  That's what I'd do, tho 
having done stuff like that before I might be better equipped to filter 
out the uninteresting entries.  But you gotta start somewhere. =:^)
