	To ja prave nevim jestli pres lspci zjistite. Mam pocit ze
tam jde zjistit, jakou frekvenci to zarizeni podporuje, ale ne na jake
ted prave bezi. Nektere drivery to umi vypsat ze zarizeni samotneho,
ale nevim jestli PCI config space neco takoveho obsahuje obecne,
nezavisle na zarizeni.

	Treba ftp.linux.cz (Tyan S2881 tusim) mi o sitove karte pise
v dmesg od sveho driveru toto:

eth0: Tigon3 [partno(BCM95704A7) rev 2003 PHY(5704)] (PCIX:100MHz:64-bit) 10/100/1000BaseT ...

Zatimco lspci -vv pise toto:

	Pricemz pravdu ma dmesg - i v manualu desky pisou ze tato
on-board sitovka je pripojena pres interni 100MHz 64bit PCI-X link.
