At this stage of the project it was too risky to use 2.6.28. But I did the minimal porting work, to see how 2.8.28 behaves on this hardware, and I thought that I saw this long delay on 2.6.28 as well as on 2.6.26. I was wrong. The reason for long delay on 2.6.26 is nand ecc code, which was since completely rewritten. After I've copied new drivers/mtd/nand/nand_ecc,c to 2.6.26, the delay disappeared.
