Ok, this is what I have dug up.
V4-4400 is a 143 mhz single chip VSA-100
V4-4800 is a 166 mhz single chip VSA-100, the docs I have only list an AGP part, with or without DVI/TV options.
What they don't list is the ram size, but they do show a 4500 with the same board options and speed.
So logic would suggest that the only difference would be ram size, then *IF* that is true a 4800 is a single VSA-100 clocked at 166 mhz with 64 MB of ram.
Thoughts?
Still doesn't answer what a Daytona with 32 mb would be

Though looking at one of the pictures above gives me another thought.
The 4200 above is listed as a Voodoo4-2 4200, so if is a VSA-101 perhaps all that was done was to add a -2 to the part number?
For example a V4-4500 with a Daytona chip would be a V4-2-4500?
/scratches head.
Were missing something, I think they were just slapping names on at random at some point, lol.
