USR2450 reflashed finally

I got a USR2450 reflashed. I used a Pretec 2MB linear flash.
I had to go to an old image on Keith Smith's archive;
newer ones don't checksum correctly so I did not trust them.
Anyone else noticed this? I already wrote to Keith about it.
I used sram.2001-06-11.img

I have read comments in archives on making an image to fill
up cards > 2MB; why do you care about this? Doesn't the
AP only load the lowest 1MB of the card anyway?
