It is reproducible for me, too, with the 128Mbyte card. Full logs are
here:

http://www.dea.icai.upcomillas.es/romano/linux/info/lk2624-rc1-mmc2/

a rapid grep shows at boot: 

Nov  5 08:45:40 rukbat kernel: [   26.538165] sr0: scsi3-mmc drive: 24x/24x writer dvd-ram cd/rw xa/form2 cdda tray
Nov  5 08:45:40 rukbat kernel: [   38.456554] PM: Adding info for No Bus:mmc0
Nov  5 08:45:40 rukbat kernel: [   38.456634] mmc0: SDHCI at 0xd0100800 irq 16 DMA

and when loading the card: 

Nov  5 09:21:14 rukbat kernel: [ 1632.002723] mmc0: new SD card at address e32f
Nov  5 09:21:14 rukbat kernel: [ 1632.002947] PM: Adding info for mmc:mmc0:e32f
Nov  5 09:21:14 rukbat kernel: [ 1632.024011] mmcblk0: mmc0:e32f SD128 123008KiB 
Nov  5 09:21:14 rukbat kernel: [ 1632.025327]  mmcblk0: p1
Nov  5 09:21:15 rukbat hald: mounted /dev/mmcblk0p1 on behalf of uid 1153

(I've trimmed away the spam by NetworkManager). 

and opening the folder in Nautilus:

Nov  5 09:21:43 rukbat kernel: [ 1654.235333] FAT: Filesystem panic (dev mmcblk0p1)
Nov  5 09:21:43 rukbat kernel: [ 1654.235893] FAT: Filesystem panic (dev mmcblk0p1)
Nov  5 09:21:43 rukbat kernel: [ 1654.235915] mmcblk0p1: rw=0, want=575135, limit=245919
...ad libitum.

and it's definitely a regression, the card is read under 2.6.23. I've
not a lot of time in my hands now, but maybe the next weekend I can try
a bisection...
