You have an nvidia kernel and X driver version mismatch. Your security update 
must have upgraded or downgraded either the kernel module or the X driver but 
not both.

Actually that's a really big version difference, and it may be that the kernel 
module version is the nvidia "legacy" driver. 173.* is really old too, but 
it's definitely part of the mainline driver series.

I don't know how Mandriva packaging works; see if you can't adjust the 
installed package versions so that the X driver and kernel module versions 
match.

That's assuming you haven't compiled the driver yourself, but if you did then 
I don't suppose you'd be confused by this error.
