UPDATE, I just found a possible solution for PB4 not waking up from sleep using a SSD:
The solution was posted in the user comments by Jordan:

NEEDS A LITTLE MODIFICATION FOR USE IN POWERBOOK 12" otherwise the HDD will not wake up from sleep.
- None so far!
Other Thoughts: First of all, I bought 128GB version and experienced the same symptoms as Snakedoc initially. ("stall and sometimes freeze when I woke my powerbook g4 up from sleep mode...and from time to time I would have to force a restart by holding down the power button")
Before I did anything - I found another review - stated that all you have to do is to make sure the HDD.. oops SSD's jumper setting is "Master."
To achieve this with Powerbook 12", I did have to use the default jumper pin that came with the drive and to do that I needed to take away a piece from the 44 pin connector so that it could accomodate the jumper pin. I used my trusty Moto-tool.
After changing the SSD jumper setting to "Master," everything is working great! Everything is really fast, stable and efficient.
I will recommend this drive if you know the difference between Slave and Master, and not scared to do a little (3 min.) operation on the connector. 🙂
