Yes, it's possible, but you might have to "degrade" to 8.1 to get the driver support from Promise. if you hit promise's site
http://www.promise.com go to the site map (since konq and moz both seem to have problems diplaying the support link) hunt for downloads on the page, and lookup the TX2000. Download the latest driver for the tx2000, and you'll see that our 20276 is part of the package. Promise only seems to keep decent tabs on RedHat and SuSE, but they don't tend to stay up with the latest greatest very well. However, if you can get 8.2 up on another box, you can download the partial source and compile your own driver. It seems that you have to do the compile on whichever distro/version you want to run the raid on (assuming they haven't released an official version) which is almost a catch-22.
However, you can get the partial source by choosing TX2000 as the product; Driver as the type and Other as the OS.
You might also try using the SuSE 8.1 driver from Promise, but I've had no luck with using an "old" driver version with a new distro version myself.
As a last note, follow the intruction to a "T". If you don't, things won't jive for you.
Hope I've helped.
If you can't get 8.2 installed on another box, and you aren't willing to go with 8.1, then you'll have to wait on them to release an update driver.
For RedHat 9, it took them about 2 months to get the "gold" code out the door. If memory serves me, SuSE 8.2 is also already supported, but any other new distros (Past RH9/S8.2) aren't yet. (Mandrake 9.1 for example)
