I've taken the 2.6.33 code and forward ported it to v3.3 in my git
tree. I've been incorporating the patches posted to lpclinux.com.

Bangaragiri --- which peripherals do the lpc31xx and the lpc32xx
families have in common?

I know I2C is common and the lpc31xx uses the common driver.
LCD is completely different.
No Ethernet on the lpc31xx.

What about USB? There is code for a NXP variation on EHCI in the
lpc31xx port, does the lpc32xx use the same EHCI block?

Does the lpc32xx have the same event router for interrupts?

What about the rest of the peripherals?
