Philips SAA9730: anyone?

[DiTBho]

So, the Philips SAA9730 is a ~20 old bit combined multimedia and peripheral controller used in thin clients, Internet access terminals, and diskless workstations, that implements
  - the VGA interface and Video RAM
  - two USB interfaces
  - PS/2 Keyboard and PS2 Mouse interface
  - I2C interface to serial EEPROM
  - Serial Debug RS232 Interface
  - Ethernet interface

I found it on a board, and as far as I can see from feedbacks in Linux, this chip was/is known to be weird, but I don't find details: has anyone ever worked on it?
I'm tempted to support it, but it might not be worth it and so I might opt to bypass it altogether.

Let me know

thanks, I have the pdf, I am looking for feedbacks, specifically for Linux.
This chip looks ... very complex.
