What is your board going to do? We have a new DSP (SHARC ADSP-2126x) and Altera Cyclone module and board coming out very soon. It is designed for embedded applications. Details will be on our web site in the next few weeks.
this one looks like what I've been looking for a while (a bigger FPGA would be better but what can i do ? ;o) However, anyone knows whats the status of the USBhigh-speed drivers for Linux ? XEM3001's apparently using Cypress CY68013 FX2 - is it supported under Linux ?
That would depend on how you program it. Class drivers for all the major types of devices exist, so if you program the FX2 to look like a serial port, or a hard drive, and you properly set the class ID in [r]enumeration, it'll just work.
If you program it differently, there's libusb which allows you to write "drivers" in user space, built into your app. libusb lets you fiddle with the low-level USB communications straight from your app, elimininating the need for a kernel-mode driver, but restricting operation to your application (or library, if you write your "driver" as one).
I haven't played with the FX2 personally yet, my devel board hasn't arrived from Bulgaria(!)

yet, probably next week. I've done a fair bit of research in advance of getting it though (and I've written Linux kernel drivers before)... ;-)
The interesting thing about the FX2 in conjunction with an FPGA is its AUTO mode, which is used by

the project that alerted me to the ELRAsoft board. His firmware literally consists of setting up a bunch of registers, then executing an inifinite loop flashing an LED. The FX2's FIFO handles everything else, clocked from the external device.
