[maemo-developers] Firmware 4.2007.26-8 has inferior SDHC performance than 3.2007.10-7 - why?

Can anyone from explain why the performance of SDHC cards is reduced when compared with the performance of the patches made available for the 3.2007.10-7 firmware? The new firmware achieves only 50% of the read performance possible with the old patched kernel (5.6MB/s when 11.99Mb/s is possible).

I opened bug 1426[1] as an RFE for SDHC support and posted this question there as a comment (with timings before/after) but as this bug is now officially "resolved" I'm not sure anyone will read it, hence my reason for posting here. I'd be grateful if someone can comment against the bug with details explaining the need for the reduced performance.

Many thanks
