Description:

recent news http://lwn.net/Articles/328533/ seems to let me think it could be a good idea to enable CONFIG_STRCIT_DEVMEM in the configuration of the kernel

i couldn't find much doc about that option but it seems it could not cause harm. (To be confirmed)
even the recommendation in the kernel help configuratin is to say Y(es) to this option

it's in kernel hacking -> filter access to /dev/mem
This task depends upon

I personally use a custom kernel, and use this option since many time without any problem. Al least X works OK. Don't know about svgalib and others that access /dev/mem, except "ddcxinfo-arch" fails with it.

I think the same... Yes to CONFIG_STRICT_DEVMEM. :)
