wine users - Apr 2008 - Wine suspending itself? (WoW on laptop with i945GM graphics)

I'm experiencing some real weirdness trying to get WoW to work in Wine on
this laptop I have.  It works pretty well (if a bit slow, but I'm willing to
attribute that to the Intel graphics hardware) except that, at unpredictable
intervals, the Wine process will suddenly freeze -- graphics stop updating and
sound goes into a loop.

The thing is that, if I run it from a terminal window, I can suspend the process
with a Ctrl-Z, type fg to resume the process, and it runs again (until this
happens again).  Even weirder, sometimes the process will suspend itself
outright -- the terminal window shows a prompt and I can type fg to resume.

Now here are some details about the system.

The laptop is a Dell Latitude D620 with 2GB of RAM.
Graphics hardware: Intel 945GM -- from what I gather it has 64MB of video RAM
itself but is meant to grab system RAM for its own use when it needs to.
OS: Fedora 8, kernel 2.6.24.4 (-64.fc8)
Wine version: 0.9.58 (-1.fc8)

Things I have tried: turning sound off completely (both in winecfg and within
WoW), turning sound on, too many variations on graphics settings to count,
booting with kernel parameter of mem=2039M or even lower, running windowed,
running fullscreen, running fullscreen in a virtual desktop, running windowed
within a virtual desktop ...

Anyway, Wine gives me no messages at all when this freeze happens.  Does anybody
have any suggestions, including suggestions for more information that might help
diagnose the problem?

To answer my own question, this behavior ceased to happen when I added the
kernel boot parameters

noapic nolapic

to the kernel command line.
