all, hi I want to port the GNOME or KDE to AMCC PowerPC 440EP board. I want to know whether it will run and whether the monitor work if I use PCI to connect the monitor card? Thank you very much!

Gnome and KDE themselves should just work... The problem is to get a video card working. The main issue is to soft-boot it with some kind of x86 emulator such as x86emu. Once that's done, the second main problem is that 440 tend to have PCI memory space above 32bits, which totally defeats broken X hacks through /dev/mem. There's a way to work around the later by doing a kernel tweak to create a "window" in /dev/mem that gets remapped to the appropriate PCI space, but you still need to fake the card base address for X ... pretty hard overall (doable though).
