128MB Memory mini2440

After receiving it last week, I've just had a chance to power up my latest
mini2440, thought I'd post the details from the bootup.

s3c2440-nand s3c2440-nand: Tacls=3, 29ns Twrph0=7 69ns, Twrph1=3 29ns NAND
device: Manufacturer ID: 0xec, Chip ID: 0xf1 (Samsung NAND 128MiB 3,3V
8-bit)
Scanning device for bad blocks
Bad eraseblock 241 at 0x000001e20000
Creating 4 MTD partitions on "NAND 128MiB 3,3V 8-bit":
0x000000000000-0x000000060000 : "supervivi"
0x000000060000-0x000000260000 : "Kernel"
0x000000260000-0x000040260000 : "root"
mtd: partition "root" extends beyond the end of device "NAND 128MiB 3,3V
8-bit"
-- size truncated to 0x7da0000
0x000000000000-0x000040000000 : "nand"
mtd: partition "nand" extends beyond the end of device "NAND 128MiB 3,3V
8-bit"
-- size truncated to 0x8000000

Don't know if its my imagination, but it appears to boot faster than the
64MB version.

Is it possible, just to replace the NAND chip on the board, to get the
128MiB Flash or do I need to modify some other things?

Where did you get this 128Mb variant? That would be very useful for my
application.

I have read somewhere that it is not advisable to replace the NAND, because
the traces come off easily even with tools. If you want to boot a bigger
image (android: >64MB) it is possible to boot from SD. I forgot the link,
where Ive read it.
