This may not be related, but I had a problem with blockdev --getsize in Fedora
14 returning the wrong size for an IDE drive on a USB-IDE/SATA adapter.  It
returned the correct size for SATA drives on the USB adapter, and for IDE
drives connected to the internal IDE port.  So I chalked this up to wierdness
on the (nearly obsolete) USB/IDE interface.  But your problem suddenly made me
not so sure.
