yes I do.
EXPERIMENTAL in the kernel config in practice is meaningless; it hardly
ever gets removed even after years of high production use of stuff. I
wonder if the EXPERIMENTAL got removed from EXT3 yet .. ;)

I assume that since your driver was written with linux in mind, that it
is gpl, right? So then you wouldn't have this problem....
(if it's not, make sure your lawyers have read the COPYING.modules file
from the kernel rpms)

The linux kernel has no ABI. So it's also not possible to break it. SLES
uses this option too afaik, and it has been there for a long time in
2.6, any driver not capable of running with it is of course very buggy
or at least not adjusted to 2.6 properly.
