Not yet, anyway.   And I'd hope that with Gateway now packaging the 
Promise card into new systems that it will be, at some point.  I 
think I recall someone mentioning that the card was supported by the 
experimental kernel, or that it was available as a compile-time

Or simply wait until linux supports the hardware.  No telling how 
long that will take, though.  It took a LONG time before any support 
was added for the S3-ViRGE chipset on my old system.

Though for some of us, plugging it into the board isn't an option.   
My brothers computer has buggy interfaces and is outside of warranty. 
Our only option _is_ to install one of those cards, at some point.  
Does that mean that he should be condemned to only using Windows?

It's a nice suggestion, if you can afford it. I, for one, cannot 
afford to shell out almost a grand (drive and controller) to get the 
amount of storage space that we need, here.  Here, at least, we have 
no choice but to wait for support for the card.  It's a shame that 
IDE takes a backseat to SCSI where development is concerned, seeing 
as a lot of us that would like to get into the linux world are in 
fact running off of IDE.
