kernel patch needed for wine?

[Sam Fourman Jr.]

Hello FreeBSD hackers.

Last Tuesday blizzard release World of Warcraft 3.3.5, and with this patch
World of warcraft stopped working in FreeBSD 8.1 amd64, it crashes
right after login.

details here:
http://bugs.winehq.org/show_bug.cgi?id=23323

in the above thread a wine developer stated the problem is this:

WoW uses opcode 0xf1 (icebp) and expects to see a single step exception,
probably as a way to detect hardware debuggers. With the kernel change icebp is
no longer raising a SIGTRAP since it doesn't set any dr6 bits, so WoW doesn't
get its exception.

Linux fixed this with this kernel patch

I have been playing World of Warcraft on FreeBSD amd64 since December of 2009
using the beta Nvidia 64bit drivers and this wine how-to

http://wiki.freebsd.org/Wine#head-6963d527c173e57b1567e881305b544d33435b6d

I can verify that on PCBSD 8.1 RC1 32bit World of warcraft works post 3.3.5
so far as I can tell it is only broken on amd64.

Would someone be able to comment on weather a patch is indeed needed
on FreeBSD amd64?

Thank you
