Hyper Threading

[Marco Cecconi <marco@evillot.com>]

Hello, which woody kernel supports Hyper Threading? I've read somewhere 
that 2.4+ kernels support this feature but how? Is a SMP build 
sufficient? How does linux support HT, dual processor style (like e.g. 
Win2000) or natively (like e.g. WinXP)?

Thank you,

Marco
