Have a look at threadx.
AFAIK thats what marvell used or purchased for the kernel in the driver.

http://www.rtos.com/page/product.php?id=2
http://www.rtos.com/news/detail/?prid=104

threadx api  http://www.rtos.com/page/product.php?id=27

If they are using threadx it would have to be in c and possibly some in asm.

expresslogic have a book on threadx  Realtime Embedded multithreading
http://www.amazon.com/Real-Time-Embedded-Multithreading-Using-ThreadX/dp/1578201349/sr=1-1/qid=1167474769/ref=pd_bbs_sr_1/002-5034521-8430408?ie=UTF8&s=books

Be interesting to find out if the driver was written/built for arm or
thumb instruction set (arm core).
