I've run thousands and thousands of RTL8019AS's from the output of a Cypress CY2292F with no problems.
Yup. Original application for the part was a

Thank you again, Matt
It contains the MAC address:
And stuff like base I/O port address, interrupt and bus size. Also a bunch of plug and play registers I've never fiddled with.
