kalyway 10.5.2 to 10.5.6 direct comboupdate?

[nagu]

Dear All,
First post. Thanks for the community
I have AMD system, which runs kalyway 10.5.2. Its been pretty stable and i havent found problem as such. (touchwood) running tons of apps luckily no issues.

I want to update to 10.5.6(mostly greed and partially need...for iphone dev)

I am trying to use ASU latest from the sticky. It lists a comboupdate for 10.5.6. would it be safe to go for this directly? Is there any precaustions i need to take (ofcourse other than backing up kexts and data). Any separate steps?
I see somewhere ppl talking about deleting some "power.." kext etc. Not sure. "The seaside place" has a kalyway update for 10.5.3 but it says its only for intel. So just wondering..if somebody can help.

Please help
