No sound, unbootable system

[PaX Team]

with kernel 2.6.24 and the newest stable version of grsecurity, the initrd problem has disappeared. But I still have problems with sound in KDE. As I was now able to check which kernel configuration option causes the lack of sound, I found out that it occurs when "Restrict mprotect" is enabled.

Does anybody know in which binary I must turn the MPROTECT flag off? Or how can I find that out myself?

before you go on a chpax (paxctl is preferred btw) spree you should figure out what exactly interferes. e.g., is it text relocations or GNU_STACK (latter can be often fixed with execstack -c)? since it's a KDE specific problem, check which binaries are responsible for sound on KDE (i think it has artsd or something like that) and you can use strace to see if any executes a failed mprotect syscall.
