I changed the 7200rpm hard drive in my MBP for an SSD drive, but I don't think that the computer or the OS is initially accessing it correctly.
The time between turning on the power button and seeing the apple logo is about 15 seconds, which is worse than it was with the old drive in. That was about 5 seconds.
Initially, the time with the SSD was 45 seconds, but after doing a reset pram and the SMC and that helped to cut it down to 15 seconds.
These fixes lead me to think that there is something at the basic bios or OS level that may be interfering with the quick startup.

Everything after that point is a lot faster with the SSD, including the rest of the startup and the loading of applications, but there is something going on at the initial startup that causes the process to delay.

Any suggestions or advice would be appreciated.

Background info:
The drive in the laptop wasn't the original one.
I had previously upgraded from the original 160gb 7200rpm drive that came with the MBP to a 500GB 7200rpm drive with no problems.
I used Superduper to clone my OSX to the SSD and then put the SSD into the MBP.
I had no technical problems along the way.
The only difference is that the old drive had two partitions because I had Windows on Bootcamp on it and OSX, but the SSD drive is just OSX because it's not really big enough to hold both Windows and my Mac stuff.
The MBP is a 2007 17" 2.4ghz Core 2 Duo with 4 gb ram and OSX 10.6.4

MBP 2.4ghz 4gb ram and Mac Pro 2.8 8 core 16 GB ram, Mac OS X (10.6.4)

    Would reinstalling the OS using my snow leopard disk and the 10.6.4 combo updater over all of the existing software be a useful thing to do?
    I don't want to do a complete reformat and reinstall of the OS and all my software now because it takes over 6 hours, but I don't want to introduce new instabilities by just installing OSX over the existing setup.
    In my previous experience with Windows, the best way to set up a new drive was to go through the entire installation process, otherwise there could be performance or stability issues.
