I just reinstalled 10.5.2 on my main desktop computer after having done some upgrades to it and our other computers. I tried out Zephyroth's ASU and it installed the 10.5.3 upgrade perfectly. I even loaded the 9.3 modbin kernel after that worked so well. Looks great to me. Here's how my Desktop looks now (previously this MB was in my HTPC):

It's essentially my "2nd working Zephyroth 10.5.x Install":
