No, 2.4 needs more work because is unmaintained by MTD. So it's better
to start with 2.6

Yes, I use a Nand Flash on my microblaze board. I use YAFFS file system
on 512Byte page nand flash.
I picked last version of MTD with kernel 2.4 support and integrated it
in uclinux. The main work is to write a custom driver for your core.

I can't help on this, never tried SPI flash.
