I must admit, I have done no real work with the STM32 yet. Only for the
infrastructure, mostly to get the stlinkV2 running on linux and the stlinkv1
run unbinded from the kernel sg driver. 

https://github.com/karlp/stlink branch uwe_usb

I haven't heard bad things about the 29.04.2011 toolchain yet, but neither
good ones.

Why not go for the F407 and the STM32F4DISCOVERY. You get the stlink
debugging/programming adapter, some devices on-board to test and all MCU pins
brought out to connector pins.
So for developping Ethernet, you would need a "ethernet shield", with the
arduino speech. 

If you tell me what PHY you would like, I could perhaps etch you a board...

Otherwise a STEVAL-PCC010V2 and a ST Link2 Adapter at around 130 Euro 
without VAT could to get you started. I could perhaps lend you.

If you need only access to the STM, the STLink is fine. As lementec fabien
<fabien.lementec at gmail.com> in the STLink group has the STLink source code,
I hope to get more specifications and can perhaps make the stlink more
useable as general JTAG programmer in my xc3sprog, or there is perhaps an
easy way to exchange the STLink firmware via DFU and run
https://github.com/gsmcmullin/blackmagic branch stlink
on it

But no "industrial-strength" solution yet.
