Over the past week I have had a number of conversations with Dell UK Sales - summary as follows:
1. They tell me that the A01 is not scheduled to be released until at least February
2. Most of the issues found on the A0 have been resolved and the units shipped now reflect this.
3. Other issues could be 'subjective'.
4. There are no units of the old model being shipped...
5. They have never heard of 0G286H or OCX268. Sales don't have access to this information. Model numbers change so frequently, they are for the factories use only and not meaningful for customers
6. Monitors are made to order and not provided from stock!! (ha ha)

My two cents, from my experiences. DISCLAIMER: this is provided "as is" and with no guarantee this is correct. This is only deducted from my own experiences and readings...
2408 for Europe are produced in CZ (Theck Republic).
The initial part# worldwide was 0CX268.
The firsts 2408 0CX268 (from Feb2008/March2008) had often a lot of of issues: bad color homogeneity (pink hue), dark side/corner.
0CX268 was progressively improved. 0CX268 models from May 2008 are ususally better than the ones produced in March for panel/color homogeneity.
It seems that some changes was made to the 2408 design in july, resulting in a new part# dependent upon the plant producing it:
0G286H for 2408 from CZ (Europe)
0G291H for 2408 from China (Australia, etc)
0G283H fro 2408 from Mexico (USA, Canada, etc).
Generally, users of 0G2xxH report the model is improved compared with the 0CX268: better anti-glare coating, better colors.
But it also depends on the built-date of the 0CX268 as 0CX268 from May are already far better than 0CX268 from Feb.
However, 0G2xxH seems to sometimes have a very small bright dot (not a dead pixel) near the center of the screen. As this not visible from a normal usage distance and furthermore only on a very dark background in low light conditions, this could normally be ignored.
All this is totally independent of the new firmware.
The new firmware improves: input lag, sharpness setting, power save mode.
It has nothing to do with picture quality or panel homogeneity.
So at this moment (transient period) it exists new part# 0G2xxH revA00 with the old firmware and part# 0G2xxH rev A01 that has the new firmware.
0G291H and 0G283H rev A01 are now delivered in USA, Canada, Australia, etc.
HOWEVER, AFAIK NO 0G286H with the new firmware (rev A01) have been yet seen in Europe.
To be complete: in the refurbishing process it seems that 0CX268 are now flashed with the new firmware. So users getting a refurbished 2408 as a replacement in Europe could get a 0CX268 rev A01.
Last thing: normally sales people should be able to check the part#.
Hope this help
