I have now updated the main article with a compiled .PKG version of AsbestOS v2.0 and a video is included.Sponsored Links
I'm not sure how this graf's driver is implemented as I've not had a chance to look at it yet, but certainly it's quite likely to be very slow accessing video memory as the CPU read speed to VRAM is very slow. You can read more about it here: noeman.org/gsm/sony/10307-rumor-ps3-slow-broken.html (where local memory means local to the GPU).
The PS3 swap driver for OtherOS gets around this by using the RSX to transfer data between main RAM and VRAM because the RSX has pretty good access speeds to both. I'm guessing this should be trivial to port to asbestos, and possibly this is what's being used anyway.
Today graf_chokolo has updated his PS3 Linux Kernel again. To quote from: dukio.com/grafchokolos-ps3-linux-kernel-updates.html
He also released Dispatcher Manager Utilities for PS3 Linux: git.dukio.com/gitweb.cgi?p=ps3dm-utils.git;a=summary
Another update from graf_chokolo is below as well:
