Current motherboards do 8GB of DDR2 (4x2G), which in dual-channel has 
17GB/s (PC2-8500, 1066MHz, x2). That is more than the FSB of any cpu can 
  handle (even twice of the 16xPCIe)

For more, e.g. 16G+, there are server boards, which offer multiple cpu 
sockets.. usually a required feature as you need to process that 16G of 
data somewhere :)

My opinions:

  - flash raid controller @ SATA2 or PCIe is interesting product if it 
can handle 8-16G CF or USB sticks - in count of 4 to 8 (hw raid5,6, 
hotswap) ... suitable for read intensive applications (mass-webhosting)

  - memory based: what about to hack a motherboard to backup the main 
memory and modify the system bios to preserve certain areas of it at 
POST? Perhaps using linux bios it can even emulate a boot drive (or 
preload the contents from a backup flash which was stored when power was 
lost (from battery backup, as standalone ram based SSD do)  ... suitable 
for read/write intensive applications - database server - the solution 
gives the fastest access and adds persistence by the flash,battery&bios.
