To quote: The repository which is based on Linux 2.6 kernel, has several wicked stuff in it especially graf_chokolo’s ram block device. As kmeaw said; “It can read/write anything in PS3 RAM, and very useful for HV hacking”

You can read below the commits done to his version of Linux kernel.

• Added support of several storage regions to PS3 storage library
  
• Improved PS3 disk block device driver
  
• New drivers for PS3 NOR and 3 RAM misc driver for full access to HV memory
  
• Added new HV calls
  
• Added extra debug messages for SPU isolation
  

Finally, from http://ps3wiki.lan.st/index.php/Custom_Firmware_with_OtherOS%2B%2B: PS3 CFW Custom Firmware with OtherOS++

• First we need a custom Hypervisor (lv1.self) with OtherOS++ support and other nice features like full access to HV services :-) (working on it)
  
• Second, we need a program like otheros.self which will resize VFLASH region and store there petitboot
  
• Third, we need a GameOS program/XMB plugin which will trigger OtherOS++ boot after GameOS reboot by setting a flag on the 5th VFLASH region
