(Wtf I just replied and its not showing up?)
You sure that IDE-CF adapter works? I got some off ebay that suck.
Not all converters support DMA: http://lkml.org/lkml/2006/5/24/46
Find one that works with DMA and performance will probably be better.
This is also why M0n0wall disables DMA by default, too many problems with CF cards when the kernel tries to use DMA.
I had no problems with a $5 converter and DamnSmallLinux;
Interesting piece of information. Thanks for sharing.

I'm gonna be giving DSL a try here soon. I saw the new release of Sabayon, gonna try that out as well.

I especially like that female one for the fact that it looks like it would just plug in directly into the motherboard, I wouldn't have to worry about the IDE cable and mounting issues.(see my pics for reference)
It looks like we will be doing a comparison with a CF converter at Phoronix shortly. Just waiting on the CF card(s) to arrive.
A couple of things worthy of note. I've had several people ask me in various places if I'm worried about the lifespan of my new device.
Add to that AMD's new technology, hyperflash. Using a Flash/NAND device as a cache buffer.
This is a beautiful thread.
The Intel Desktop Board D201GLY is a powerful, almost complete
computer for $70, aimed at Intel's "next billion customers."
As others have also noted on the web, it cries out to have dozens
assembled into a cheap supercomputer, e.g. a Linux Beowulf cluster.
Just need memory and a drive, per board, supply them all power, and
network them through a switch.
I was thinking USB pen drives, till I found this thread.
On the other hand, USB pen drives would save on the conversion
hardware, and wouldn't matter after booting if one then used a RAM
You're in a whole different territory than I am.

You'd only need a high performance setup on the primary computer.
I'd probably just go with pendrives, you can get them for 10 dollars each(256mb) off of pricewatch.
Glad I could offer you a possible alternative though. :-)
I'm hoping that CF can improve Linux memory swapping perfomance.

Which Compact FLASH cards support DMA?
With a new pc with usb boot support you can directly use USB sticks for linux. Little ones with 1/2 GB are enough to run a Linux livesystem (compressed), bigger ones can hold even a hd install. The install onto usb is a bit tricky, but possible. The sticks that work have usually a 512 byte sector size, one 2 GB stick I have got has 2048 sector size - that does not work. There is a simple check for it:
blockdev --getss /dev/XXX
Older pc can be used to boot from a cd with kernel/initrd stored on it and root fs on usb. And there are much faster usb sticks than 6 mb/s...
