PS3 LV2 Kernel Peek/Poke Patched, Backup Managers and CFW!
Update: This method ended up failing because the LV2 address range is protected by Sony on PS3 with Firmware v3.55, so Netkas and flukes1 are now working on a patch for LV1 instead.
Today Netkas and flukes1 have successfully managed to patch the PS3 lv2_kernel in v3.55 Firmware to allow peek and poke syscalls, meaning PlayStation 3 backup managers and Custom Firmware (CFW) will also be able to make use of them!

From the ReadMe file:Patch to add peek and poke syscalls to PS3 firmware v3.55 by flukes1 and netkas (irc.efnet.net #ps3test)
To create the patched PS3UPDAT.PUP:
1. Use bspatch to apply PS3UPDAT.PUP.bsdiff to Sony's official 3.55 PUP, which is available from their website.
2. Run this from command line: "bspatch PS3UPDAT.PUP PS3UPDAT-NEW.PUP PS3UPDAT.PUP.bsdiff"
2. Ensure that the md5sum of the resulting PS3UPDAT.PUP is: 337831fac6a9b05074f73710c4bb7c86
I'm going to wait a little while before I jump on this. The original jb payloads did not include peek/poke. My guess is that after devs get a handle on 3.55 there will be a new CFW with only the needed syscalls added and not peek/poke.
I don't understand this release, Geohot in his video from last week he says OMG don't patch lv2 you'll brick your console. Either that was a hint at what to do to get backups launched, or this at some point will brick your console.
