Well, I've exchanged several trouble ticket messages with the manufacturer (OCZ), and it turns out that there can be a subtle problem with the drive when installed into an older computer.
I've talked with Dell technical support, and confirmed that the computer does indeed have a SATA1 interface.
The drive has a SATA2 interface, which has a higher rated bandwidth than a SATA1 interface. The SATA1 interface does not throttle the data when the bandwidth gets too high (read: saturates).
Here's a link to more information:
http://en.wikipedia.org/wiki/Serial_ATA#SATA_Revision_1.0_.28SATA_1.5Gb.2Fs.29I've posted two suggestions to OCZ for possible firmware improvements. The first is to set the drive to operate at the SATA1 bandwidth (which will go far in solving incompatibility problems like this, and still retain zero seek times). The second is to introduce a start delay, which would cause the SSD to delay the initial time it begins to produce data, to allow the SATA controller and associated drivers to become ready before the data onslaught begins to occur.
So the lesson learned is: installing a much faster SSD than what the computer originally had will not automatically work, because there are one or more corner cases where the SATA1 interface will get saturated and cause unintended results.
So for now, I'm done.
Either the customer is going to accept that the Standby functionality of the OS is not going to work with this drive, or the drive needs to be replaced with something slower.
