I found a fix for my problem ! 

I had HZ=1160 in my kernel and WITH_RTC enabled in mplayer. 

For some reason, latest kernel code doesn't like the option and panics. I 
removed both HZ=1160 and WITH_RTC and now mplayer works like a charm.

So either mplayer (or rtc-2004.02.24.1_4) doesn't like something added in the 
kernel between july 8th and today, or the kernel doesn't like the way mplayer 
(or rtc) syncs up with the clock.
