You should have one of the following-intel® Pentium® 4 dual core, Intel® Celeron® D & Intel® Pentium® D-That what the GX520-620 came with.
No USB fixes in DSDT only fix is for GMA950.
As scififan68 says ensure you have the appropriate sleepenabler.kext in Extra/Extensions
And remove the force64 part in the boot.plist just have arch=i386
My Dell GX620 have a single core Pentium 4, 3.0Ghz. I used Xbench and got a total score of 100.37 without hyperthreading and 101.32 with hiperthreading. I guess with a single core processor it doesn't make any noticeable difference. I just have 2 kext installed on the \Extra directory: FakeSmc and LegacyAppleRtc. Just that and nothing more. Everything runs just fine, even sleep but with hyperthreading off. Can you post the link of the sleepenabler kext you guys use? I'll try that with HT on.
One more thing:
On my bios i have sata as normal. I think its faster than combination. I didnt install ioatafamily and all my drives runs fine, even my IDE Dvd-rom. I'm just saying this because probably we don't need all those kexts installed if the system runs stable without them.

Thats really weird, I have the GX620 with a 2.8GHz Pentium 4 with HT and my sleep works just fine with HT enabled in bios. I do not have usb issues "built in usb" is what it says in system profiler. The only time sleep doesn't work for me is when it boot into pure 64bit mode and it just wakes up immediately, but I've heard that is because the gma 950 has no 64bit kexts. I wonder if you have sleepenabler.kext installed into /Extra/Extensions ?
Please post a link of your sleepenabler kext, Ill try that.
You have the Hi-speed Usb Bus as Built-in on system profiler? I have all Usb Bus Built-in except the Hi-Speed Bus witch is on Expansion Slot. That slows Usb 2.0 transfers and cuts power from external hard drives when the system goes to sleep. When the computer wake up, it shows you a message of a usb device removal warning.
You can read the thread of this issue here : http://www.insanelym...howtopic=155345
ApexDE on post 43 of that thread found the solution. Post 43
But i can't apply that to my dsdt. I don't have any entry for ehci (hi-speed Usb) on my dsdt for me to apply his solution. Really strange.
