Guess my P3-based laptop doesn't count as modern then:

0: 7602983 XT-PIC timer
1: 10575 XT-PIC keyboard
2: 0 XT-PIC cascade
8: 1 XT-PIC rtc
11: 1626004 XT-PIC Toshiba America Info Systems ToPIC95 PCI to Cardbus Bridge with ZV Support, Toshiba America Info Systems ToPIC95 PCI to Cardbus Bridge with ZV Support (#2), usb-uhci, eth0, BreezeCom Card, Intel 440MX, irda0
12: 1342 XT-PIC PS/2 Mouse
14: 23605 XT-PIC ide0

I can't even imagine why they did it like this...
