This was helpful. The Lacie card looks identical to the ones I listed as well. Dell appears to no longer have it. I orded the one from macsales, cause they said I could return it if it didn't work with the linux drivers.
I sure hope these controllers are more reliable then USB. Besides the poor performance, I have a PE2950 that gets I/O errors and kernel panics when I do heavy I/O to USB drives (centos 5). The same drives run fine over usb attached to my notebook. I tried to look at a kernel crash dump, but I've yet to figure out how to run crash on an image from a PAE kernel. Maybe you need to be on a 64 bit system to examine a PAE kernel crash dump.
