It may be overkill for your requirements, but on V2 and V2Pro 
architectures you can implement the controller internally to the FPGA, 
and connect to the ICAP primitive.  You can even connect it to a 
microblaze running either low level code or the Microblaze uClinux 
operating system.  There is a core in EDK6.2 (and probably 6.3) called 
opb_xhwicap that accomplishes this.  I posted a uClinux device driver 
for this device a few weeks ago.  Attached is a paper I wrote earlier 
this year that talks about what you can do with it - it may be helpful 
or interesting to you.

The group at Karlsruhe - Jurgen Becker et al, have also published work 
on self-reconfiguring systems using ICAP - they had a paper at this 
year's RAW workshop, that might interest you.

Regards,

John
