Moonlight from PS2Dev has released NO-KXploit Patcher for 1.50 PSPs, heres the info:
This program will patch the firmware 1.50 (in RAM) to allow it to run normal pbp's.
The patch will remain resident in the firmware until one of these conditions happen:
1) A program crashes the psp, forcing you to do 2.
2) You restart your psp holding the power button or remove the battery.
You can run/exit games/homebrews, put the psp in sleep mode... none of those things will delete the patch from RAM.
I don't know if someone will find this useful since most current homebrews are kxploited, but it's a solution to having 2 folders, hiding icons... and all those annoying things.
It's also an example of a program that remains resident surviving sceKernelLoadExec, sceKernelExitGame, maybe someone finds that useful (there is a part of the code that it's executed with no firmware in RAM , some cool things could be done with that)
