AVR-Chat

Anyone using this device? Got any tales to tell?

I have heard that there' no "full-blown" Linux C library for it - just a
ucLinux one. Is that still true?

Yes.

The OP is not asking about Linux versus uClinux.  The AVR32 runs 
Linux, not uClinux, for the reason you state.  The OP is asking about 
the C library.  It seems to be a version of uClibc, not "full-blown" 
libc.  My guess is that this is because the AVR32 does not have a 
keyboard, screen, disks, etc. (i.e. it is not a complete computer).  
But, I am not an expert in this area and the OP must suspect that a 
full implementation of libc is somehow possible or he would not have 
asked the question.

Does the AVR32 have a MMU?  Usuall ucLinux is used on the systems
that do not have Memory Management Units, so there many
never be a '"full-blown" Linux'.

AVR32 is a full blown processor with MMU, etc.  It is suppose to do about 3x
the mips per mhz that an ARM9 does.  The NWG100 board ($73 from mouser?) has
linux installed and the complete BSP and development environment (including
eclipse IDE) are downloadable from www.atmel.com.  The kernel has it's own
server somewhere as well.  There seems to be quite an active community
supporting it and Atmel seems to be seriously supporting GCC/Linux as well.

Also, the JTAG mkII works with the AVR32...
