Interesting indeed, keeping an eye on that forum thread, looks like some people are having success.

| People with PS3 Slim DON’T ATTEMPT! There's been a lot of reports of bricking. We can confirm that Older Fat PS3’s are downgrading just fine. Just an overview how this method works? Well while downgrading the PS3 thinks it’s on FW 3.56 which we know it’s on 3.41. The one thing we recommend is once upon downgrading is to then downgrade to 3.15 firmware, and then upgrade to 3.41 official firmware.
Here a Quick Tutorial How to Downgrade From 3.55 to 3.41
You must downgrade from 3.55 to 3.41 before downgrading to another firmware.
1.) Fully power down the PS3 Fat (toggle the power switch)
2.) Restore power to the PS3 Fat
3.) Format a USB drive with the Fat32 filesystem
4.) Open Lv2diag_355.zip and copy the file from the File1 folder (Lv2diag.self) to the root of the USB drive
5.) Copy PS3UPDAT.PUP from Downgrade.zip to the root of the USB drive
6.) Insert your payload device with PSGrade into the USB port closest to the Blu-Ray drive. Power on the PS3.
7.) The PS3 should start up in service mode. Power it down with a controller.
8.) Remove your payload device, and insert the USB drive into the same port. Power on the PS3
9.) The PS3 will downgrade, and then automatically turn itself off. Nothing will appear on your TV.
10.) Power your PS3 back on, and you should still be in service mode. From here, you can now downgrade to earlier firmwares.
To return your PS3 to normal retail functions, shut down your PS3 using the controller.
Then, repeat steps 3-4 using the Lv2diag.self from the File2 folder instead. Then, repeat step 8
USE AT YOUR OWN RISK
DO NOT ATTEMPT TO DOWNGRADE A SLIM UNIT WITH THESE FILES YOU WILL BRICK IT!!!

I copy & pasted this from theplaystationclub.com, but the source of information is psx-scene.com.
First I was going to make a news post about this, but it still seems risky as it can brick consoles, so lets keep it in the forum for now.
