problems with xf86vidmode

Hello,

1. when I try to watch a dvd with a xf86vidmode enabled binary, ogle
gets killed immediately after starting it.

I've attached the `ogle --debug` output, and here is a backtrace
from the gdb session (I don't know, if it is useful):

Program received signal SIGFPE, Arithmetic exception.
[Switching to Thread 16384 (LWP 24461)]

Ogle Version:  0.9.2 and cvs
Graphics card: Geforce4 MX
Distribution:  LFS (gcc 3.3.1, glibc 2.3.2, a52dec 0.7.4, alsa 1.0.0rc1,
               XFree86 4.3)

It is not that important, because I can watch dvd's without xf86vidmode
(configure --disable-xf86vidmode), but maybe it could help finding a bug.

2. the configure script has problems with alsa 1.x, I had to edit
configure.in to enable alsa support.

Sorry for my bad English.
