there's the mythical giga-byte i-ram ... i say mythical because i've seen
lots of reviews but haven't been able to find it for sale:

http://www.giga-byte.com/Peripherals/Products/Products_GC-RAMDISK%20(Rev%201.1).htm

the only problem with the i-ram is the lack of ecc (it could be 
implemented in a software layer though).

umem.com have what look like excellent boards but they seem unwilling to 
sell in small quantities...
