Although I have only tested with WinARM on Win32-systems the code should compile with all arm-elf-gcc-based toolchains. Maybe some small changes are needed in the makefiles. I have positive feedback from users who have compiled my projects on Linux development-computers. As far as I know gnuarm is available for Linux too so you do not have to build your own arm-elf toolchain. For flash-programming: search the at91.com-forum. Someone announced a Linux-software which can talk to the preinstalled bootloader of AT91SAM7s (SAM-BA) thru a AT91SAM7 UART. Another option is OpenOCD which can be used to flash thru the JTAG-interface. I have put a small example how this can bee done on my web-pages yesterday. Once again I have only tested with Win32 but OpenOCD is "multiplatform". Information can also be found in the OpenOCD support-forum. Compiling your your own OpenOCD from the current SVN-sources should be not problem - everything should be prepared for the Linux-envirionment. Hope this helps, Martin Thomas
I should have mentioned that Rowley's Crossworks is available in a Linux-version. It's not very expensive and maybe the easiest way to start since everything is integrated into an IDE. Theres is a (very) time-limited trial-version available. I expect they have some kind of flash-programming functions integrated. Maybe they include examples. I have never used Crossworks (and do not get money for this "advertisement").
