Nilbog: Karg and Martar Icebear will now be 8 hour spawns +/- 2 hours.
So if they are seperate spawns (aren't the PH for each other), even if killed immediately, you should see one or the other an average of once every 4 hours.
I saw one of each over a weeks time playing probably 40 hours tracking every time the button repopped on a Ranger.
Most of the times I played, the only people high enough in the zone to be able to kill them were at Ice Giants. I never saw another Ranger and the Druids were all low/mid 20s killing mammoths. I should have seen them 5x each on average.
My main on live was a Druid and I remember killing Martar several times a night too so I doubt they were on a timer at all but had PHs (not each other either).

Post from 2000 saying both Karg and Martar were up at the same time so they shouldn't be PHs for each other (in case they are here).
"This guy is tough. I've heard rumors that he only spawns when Karg Icebear has been killed, but I don't think that is true becausewhen I got my cloak from Karg, I turned around and got a fist full of Martar fist. Very nasty surprise. I only had around 250 hp at the time and he dropped me like a small child drops an expensive item in a glass shop. Stay away from him unless your lvl 38 or higher."
Here is a post from one of those forum experts (their name in green) from 2001:
"Sometimes, by the grace of the gods, another beast will spawn in his place. I have seen such forms as a "ice goblin whelp" and " a polar bear cub" spawn in his absence. It is most unusual to see a cub so far out on the tundra near the Mammie Ruins - slay it and head for the Perma Frost gate and keep tracking."
