This is the patch, as suggested by Daniel, using only the product tag for IDE/SATA.
Since qemu supports the model tag, if the drive bus is IDE OR SATA the product string gets passed to qemu using the model parameter
If the bus is either SATA or IDE, the product string can have a max lenght of 40, as per ATAPI spec in the field "model" of the
IDENTIFY PACKET DEVICE. This should be the better solution, since you do not need to rely on space checking in the vendor field.
Tell me what you think about this version, and if it is satisfactory, I will write the missing tests.
Thanks for your time and effort,
Benedek
