-tar fs buffer upgraded to 9Mb
-adding some kernel addons
With this settings i was able to fully boot a gcc2hybrid.
The x86_64 started up to the rocket, but could'nt go into Tracker.

First implementation of reading sectors from an SD card.
This is not the best performance for many reasons:
- No DMA
- Reads only one sector at a time
- Cannot read more than 512 bytes per syscall
Also there are major limitations:
- Cannot read less than 512 bytes. The hardware of course works in full
sectors. The mmc_disk driver should go through the io scheduler to
make sure requests have a reasonable size and offset, and nothing
tries to read just a few bytes in the middle of a sector.
- SD cards only (no SDHC, no MMC)
Architecture problems:
I think too much of the implementation is done in sdhci_pci and should
be moved to the upper layers. However it is difficult to say without
having implemented DMA (which indeed will be at the low level of the
sdhci controller). It doesn't help that the order of operations is a
bit different depending on wether there is DMA or not. In DMA mode you
first prepare the buffer, then run the command. In non-DMA mode you
first send the command, then read the data into the buffer. We need an
API at the mmc_bus level that doesn't care about that low-level detail.
There are other things that the MMC bus should be doing however, such
as switching to different clock speeds depending on which card is
activated and how fast it can go.
At least the following should be done:
- The read method for mmc_bus and sdhci_pci should use a scatter-gather
structure as a parameter instead of a single buffer
- See if can be integrated into ExecuteCommand at sdhci level (it's
essentially a command with an additional data phase)

- There is one single "Puase" key also acting as "Break"
- For historical reasons it sends a complex sequence (control + num lock) instead of having its own key code
