First, to both of you.... What are the models of the Macs involved here?
Second: What is the version of OSX you have installed?
Third: Were any of these machines upgraded from Leopard (or earlier) to Snow Leopard (10.6.x)?
Fourth: Look in "/Applications/Utilities/Console.app" "database searches/all messages" (click "show log list" if necessary to expose the sidebar)
Fifth: What kind of third party graphics/multi-media software do you have installed?
Jullian, from your log listing, it looks like you have definite problems with your third party software...

/System/Library/Extensions/DigiDal.kext is already loaded
I run CXG 10.1 and LOTRO (21 March update) on both my iMac and MacBook Pro. I never had a problem with the iMac, which only ever had Snow Leopard (10.6.0, now 10.6.7) installed on it. However, my MacBook Pro - which had been upgraded from pre-Leopard to Leopard to Snow Leopard was nothing but constant problems, including many, many crashes. My son had over time loaded all sorts of multi-media software on the MBP.
I finally bit the bullet, wiped the disk and did a complete re-install of Snow Leopard from the 10.0 DVDs, upgraded to 10.5 and then installed CXG and LOTRO... and it hasn't had a problem since then.
My basic theory is -- it is well known that the transition of 3rd party software from Leopard to Snow Leopard was EXTREMELY problematic, with many 3rd party applications unable to run for months after Apple released Snow Leopard -- Old pre-Snow Leopard applications created and left behind all kinds of "hacks" (ktexts) which were not sufficient to prevent OSX from running, but which interacted with WINE (CXG). Re installing the system cleared all of those and WINE (i.e. CXG) no longer had conflicts. Much of this is directly related to graphics glitches.
Back to DIgiDal ... see:

(BTW, there is no such startup command sequence as cmd-f on an Intel Mac).
Rather than use Ktext utility, which I have no knowledge about....

I would recommend that you run disk utility, then power-cycle (shutdown, not just restart) your machine.
One last point... if you have problems with LOTRO, post to the lotro forum:
