This spec seems to be dated. Guess sony has updated PSP's spec.

Final spec(PDF format) for PSP can be downloaded from SCE's official website. The doc is in japenese. The most noticeable modification is memory size.

Some of them

CPU: MIPS 4000 1~333Mhz(Seems alterable for software)
MEM: 32MB(main), 4MB(internal)--guess it is for video memory
display: 4.3 inch TFT LCD, 24bit color, 480*272 in resolution
io: headphone/mic, infrared port, high speed USB, wireless LAN(802.11b)

4MB eDRAM is 2MB (for video memory) + 2MB (for VME)
8MB out of 32MB main memory is always reserved for OS.

Right.
It is composition of

system memory manager
program loader
interrupt / exception handler manager
multi-thread manager
IO/File manager
power state manager
device driver / file system / kernel service

Whenever you press home button, you could see OS screen even if game is loading or running.
