Due to little time i was not able to contact 3ware-support yet.

But i tried to install that thing one more time. This time i downloaded a new 4.10 image and installed with that.
boot-loader _does_ work with freebsd 4.10 although it page-faults later on boot. with 4.10 i can get to loader-prompt.

4.10 has twa build in, right? it's not mentioned in the hardware-notes on
i was able to load twa.ko of a disk in loader, but that is quite unuable as twa is already build into generic-kernel.
