Erm no. The kernel is just probing the disk (well asking it). If it supports Liner Block Addressing, fine. If it sais it's pertending to be 2484/16/63 phyisically, fine too. LBA means that you can refure to 0/0/0 as block 0, and keep going up without worring about what that block is in CHS format. It's one of the ways of getting arround the bios/ide disk brokeness (like sector address tranlation lets you call that disk 621/64/63 ....).
Wether or not LBA is turned off in the bios, Linux will use it. It's only the bios that wont. Linux has supported LBA for longer than bioses have.
