ipod mini not recognized in kernel 2.6.17.6 (EFI disabled)


Hi all.
Since 2.6.16.18 (i think) my ipod mini wasn't recognized anymore. I read a lot about a couple of parches applied to the kernel mainstream, for example:
Code:
commit e9a1c52c7b19d10342226c12f170d7ab644427e2

    [PATCH] sbp2: add read_capacity workaround for iPod
    
    Apple decided to copy some USB stupidity over to FireWire.
    
    The sector number returned by iPods from read_capacity is one too many.
    This may cause I/O errors, especially if the kernel is configured for EFI
    partition support. We use the same workaround as usb-storage but have to
    check for different model IDs.

...and others. Also, i read about disabling EFI partitions.
Well, the patch and all is supposed to be in the latest kernel source and i have EFI partitions disabled. In fact, it is recognized but the usb subsystem don't assign a device file so you can't mount it.
Here is the only output i get:
Code:
Jul 20 00:11:21 gilead kernel: usb 1-1: new high speed USB device using ehci_hcd and address 4
Jul 20 00:11:22 gilead kernel: usb 1-1: configuration #1 chosen from 1 choice
Jul 20 00:11:22 gilead kernel: usbcore: registered new driver ub
Jul 20 00:11:22 gilead kernel: Initializing USB Mass Storage driver...
Jul 20 00:11:22 gilead kernel: usbcore: registered new driver usb-storage
Jul 20 00:11:22 gilead kernel: USB Mass Storage support registered.
Jul 20 00:11:22 gilead kernel: ub(1.4): GetMaxLUN returned 0, using 1 LUNs
I don't what could be happening. I googled a lot, only to find the two solutions above (didn't work for me).

Any ideas?

The ipod has the latest firmware (1.4.1) and my distro is Slackware 10.2+patches. If any other info is needed, please tell me.

Thanks...

I've just installed Rockbox firmware (http://www.rockbox.org) on my ipod and now it is recognized:
Code:
usb 1-1: new high speed USB device using ehci_hcd and address 4
usb 1-1: configuration #1 chosen from 1 choice
ub(1.4): GetMaxLUN returned 0, using 1 LUNs
 uba: uba1 uba2
usbcore: registered new driver ub
Initializing USB Mass Storage driver...
usbcore: registered new driver usb-storage
USB Mass Storage support registered.
...don't know why it just worked.

Thanks anyway!
