Great work! Now the Debian 3.0r4 installer with 2.6.11+tcx kernel almost 
finishes. Performance is also much better.

There is some problem with CDROM access, the files on CD look corrupt, 
whereas the same image used as hdb works perfectly.

Some comments on the code: Instead of adding s->bufstart, maybe you could 
use the s->rptr, as it is used for similar purpose for FIFO. Please add more 
spaces to conform to general code style.

For even better performance, you could try to avoid the memory to buffer 
copy and give bdrv_read pointer to host memory.
