There is no kernel on MMC. There is only one kernel in flash (/dev/mtdblock2)

Any further info about this? Maybe you forgot to unpack kernel zip archive and flashed it as is? Newer kernel flasher (since last week) has some additional checks to prevent this. How did the boot look like? Did you see the boot menu or at least the 'press menu key to see the menu' message? In that case kernel should be OK and it should boot from flash at least.

If it should work and I could take it back, how can I prove the seller that the card is faulty as it works well at lower frequencies?
Well it should work in theory but anything is possible. I have one card that works in everything except N800 so such things happen. Kingston mmcmobile 1 and 2GB cards were reported to work, though. Perhaps some fake one from eBay? Does you card has 2 rows on pins (i.e. is mmcmobile not regular rs-mmc)?

There is no such kernel.

Even if card is faulty, patched kernel should boot fine from flash. You can also try to remove the card when booting but it shouldn't matter.
