Sorry Kinnie,
Your info is a little out there my good friend, theres a lot of blurb on the net about what is compatible on the PS3 unfortunately if you google it, you will find some down right talking b0ll0x0rz too.

Now the PSX/PS1 never had an emotion chip. PS1/PSX titles are emulated on the PS2 and are compatible by the native emulation on the PS3 also. As with the the PS2 there are some games that have problems with the memory card, most notably is FFVII, if you use anthing other than an PSX memorycard it wont be able to read or save data, I will point out it corupeted my save data (lucky for me I have a backup save OCD).
Only the PS2 games required the Emotion Engine Hardware, which is a highly modified RISC processor. It implements the
MIPS-III instruction set architecture (ISA) and much of MIPS-IV in addition to a custom 128-bit
single instruction multiple data (SIMD) instruction set developed by Sony/Toshiba.
As hardcore as it sounds its easier to emultate than a PowerVR chipset (think Dreamcast) as such you can play PS2 Games on the PC =D
Before getting the PS3 for chrimbo, I did infact wrestle with the do i get the 60GB PS2 compatible version?! .... then though... I have a PS2.... with a harddrive.... why would I want to pay more for an older (pre-used) model that is infact defective (YLOD) by design? (even if Sony wont admit it)
I have a PS2 with hardrive, its both Hard-Hacked with a Modbo760 modchip and the McBoot exploit, the latter is not needed and I can load to a Nix OS to then load any oy my programs. at the moment its set to load direct to HDLoader 0.8c
Also the PS3 will also convert PSX games for use with you PSP, if memory serves me, I have a PS3 here at the house (its the house christmas present) so I will let you know how I get on with the later =)
so, all PS3 will play PSX games via native emulation, however unless you have a specific model (60GB version) you wont be able to play PS2 games.
HOWEVER, you could install linux on your PS3 and then run a PSX/PS2 emulator from there =D
