Does Linux do anything About SSD Performance Degradation?

I have been thinking about getting an SSD for my laptop but just read this article on performance degradation of SSDs: http://www.anandtech.com/show/2738/8

I typically use ext4. Does anyone know if any of the Linux filesystems/kernels/etc do anything about SSD performance degradation? Has anyone found a solution to this problem? Maybe new SSDs don't have the issue?

I think TRIM is supported from kernel 2.6.33 onwards for SSD drives that support it in the SSD firmware.

There is a good Arch page about SSD's here

My OCZ Vertex 2 SSDs slowed down just a tiny bit soon after installing them, but TRIM seems to be working well and they don't seem to be slowing down any further. I'm running them on ext4 with journaling enabled, and only the log files are being directed to temp files.  Everything else is going to the SSDs, and they are being used just like regular hard drives.
