The wrapper may be fine, but do the drivers work?  This is the main
reason (afaik) that www.linuxant.com has provided their version of the
FC2 kernels with 8K stacks here:

>From their "known issues":
Some drivers need significant stack space. Kernel stack size on Windows
is generally 12k (3 pages) but only 8k - sizeof(task_struct) = about
6.5k on Linux. Stack overflows, although rare but still theoretically
possible can lead to semi-random crashes. This is even more likely to
happen when using kernels compiled with CONFIG_4KSTACKS (which is the
default in Fedora Core Test).
