Kernel boot hangs during installation

[Paulino Calderon]

Ive got a Toshiba Satellite P10-EE1 with the following specifications:
-Intel(r) Pentium(r) 4 Processor 3.20 GHz processor with Hyper Threading
Technology, 533MHz PSB
L1 Cache 12KB/8KB (instruction/data), L2 Cache 512KB
-Disk drive 80 gb : TOSHIBA MK9026GAX
-Video card: ATI MOBILITY RADEON 9700
-TOSHIBA DVD-ROM SD-R6112
-Atheros Wireless Network Adapter

Well first I tried to install freebsd 5.4 without success, i cant get it to
boot, my installation cd works ( ive tried on different machines ), I get
the menu with the ASCII daemon and let the countdown time out, but then it
hangs when it tries to boot the kernel. Ive tried the acpi off and safe mode
and the same thing happens, so i thought this might be a incompatibility
problem so i waited and tried the 6.0 RC1 and still no luck, any help or
orientation you can give me would be really appreciated, thanks.

Greets.
