Sleeping Macs reboot
Many Mac owners are crying out to Apple for help with an issue that seems to have cropped up only recently, resulting in erratic and mysterious reboots when attempting to awaken a sleeping Mac. Users on Apple's own support forums are posting in droves about various Mac systems with the issue, though most affected systems appear to be Mac Pros and iMacs. One solution which has worked only for a portion of those affected is to reset the Mac's PRAM and SMC, while still others report no changes in their Mac's behavior.
Some users report the problem occurring just after installing third-party memory, others say the mysterious reboots began occurring on a newly purchased machine with stock memory and no peripherals attached. One user who runs Windows Vista natively under Boot Camp says his Mac Pro sleeps and wakes normally in Windows, suggesting that the problem is not hardware based but is rather an issue with Mac OS X itself.
One Mac owner promised to return his Mac for a full refund and wait to purchase a new Mac until Apple fixes the problem, stating that after working for seven years with a "flawless G4 Cube" he has no desire to "downgrade to a buggy computer" that cost him €2,500.

"recently"?
My MacBook was doing this for a year. It finally stopped after I disabled some feature in generating the sleep image. It also managed to fix my machine's problem with not seeing my home wireless on wake. I just wish I could remember the command I executed to do the disabling.
