If you're also considering 8051 derivatives, look into the Maxim (Dallas Semi) DS80C4xx-based TINI board. It's about $140 or so with shipping and includes a huge amount of flash (1/2 MB if I recall correctly) and about the same amount of external static RAM and 64KB of internal static RAM. It doesn't have USB, but it does have 10/100 ethernet. It has a full TCP/IP v4 network stack in the onboard ROM. It can download via that ethernet with TFTP. It's a very capable processor indeed for the size.
I have written small amounts of code using the SDCC for this target with no problems so far. I must admit not having written a lot of code yet, so that last statement has to be qualified. There are compiler options to directly support the 80c4xx and its 24-bit addressing modes. There are a few libraries supplied by Maxim targetted specifically for SDCC, in fact that is how I learned about SDCC initially. Just go to Maxim's web site and search for DS80C410.

I would like to have a few KiB of RAM (I'm going to implement hashfunctions to run on it). Also the Chip should be well supported by SDCC as I would prefer using an free compiler. Also development is done on a Linux machine so there should be tools available to load code into the µC for this OS. I would also prefer a flashing method via USB instead of RS232 or selfmade cables. And how is debugging working on those µCs? Is there JTAG? And if, is it supported by linux based utils? A lot of questions, and thanks in advance for reading it and answering.
